A new synthetic route of 2077-19-2

According to the analysis of related databases, 2077-19-2, the application of this compound in the production field has become more and more popular.

Reference of 2077-19-2, Adding some certain compound to certain chemical reactions, such as: 2077-19-2, name is 2-(4-Bromophenyl)propan-2-ol,molecular formula is C9H11BrO, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 2077-19-2.

In a 250ml 2 necked round-bottom flask equipped with a condenser and under argon were dissolved 5.3g of N4,N4′-di(naphthalen-1 -yl)-N4,N4′- diphenylbiphenyl-4,4′-diamine (NPD) and 4.2g of 2(4-bromophenyl-2- propanol) in 65ml of dichloromethane. Then 3.15ml of BF3, Et.20 were added dropwise under stirring at room temperature. The reaction was monitored by thin layer chromatography (TLC). After completion, the reaction medium was filtered through a silica gel plug. The plug was rinsed by 25ml of dichloromethane. After removal of the solvent under reduced pressure crude product was recovered and purified by flash chromatography over silica gel using a mixture of 50/50 v/v hexane/dichloro methane as the eluent. 8.1 g of pure N4,N4′-bis(4-(2-(4- bromophenyl)propan-2-yl)phenyl)-N4,N4′-di(naphthalen-1 -yl)biphenyl-4,4′- diamine was obtained. Structure was confirmed by NMR.

According to the analysis of related databases, 2077-19-2, the application of this compound in the production field has become more and more popular.

Extracurricular laboratory: Synthetic route of 2077-19-2

With the rapid development of chemical substances, we look forward to future research findings about 2077-19-2.

As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 2077-19-2, name is 2-(4-Bromophenyl)propan-2-ol, molecular formula is C9H11BrO, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Safety of 2-(4-Bromophenyl)propan-2-ol

Step 1: 5-Amino-1-(2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole-4-carbonitrile from step 1, example 15 (500 mg, 2.1 mmol), 2-(4-bromophenyl)propan-2-ol (519 mg, 2.41 mmol), and cesium carbonate (1.03 g, 3.15 mmol) were taken up anhydrous toluene (14 ml). The mixture was degassed with argon and bis(tri-tert-butylphosphine)palladium (107 mg, 0.21 mmol) was added. The mixture was again degassed with argon and then stirred under argon at 120 C. for 4.5 hours. Additional 2-(4-bromophenyl)propan-2-ol (50 mg) was added and the mixture heated for 2 more hours. The material was cooled to ambient and stirred overnight. The crude was filtered through a plug of celite, rinsing well with ethyl acetate (60 ml). The organic layer was shaken with water (60 ml) in a separatory funnel and collected. The aqueous phase was back extracted with ethyl acetate (2×40 ml). The combined organic phase was dried with magnesium sulfate, filtered and stripped. The remainder was purified through Analogix flash column chromatography using ethyl acetate in hexanes (10% to 45% gradient, 23 g silica gel) to provide 5-(4-(2-hydroxypropan-2-yl)phenylamino)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole-4-carbonitrile as a red-brown viscous oil (482 mg, 62% yield). LC/MS calc’d for C19H28N4O2Si (m/e) 372.55, obs’d 371 (M-H, ES-).

With the rapid development of chemical substances, we look forward to future research findings about 2077-19-2.
