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. 2919-23-5, name is Cyclobutanol, molecular formula is C4H8O, 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. Recommanded Product: Cyclobutanol
Intermediate 12Carbonic acid cvclobutyl ester 4-nitro-phenyl esterA solution of 4-nitrophenyl chloroformate (6.00 g) in dichloromethane (12 mL) is added dropwise to an ice-cooled mixture of cyclobutanol (2.00 g), and pyridine (2.4 mL) in dichloromethane (10 mL). The resulting mixture is stirred over night at room temperature. Water and dichloromethane are added and the organic phase is separated, washed with brine and dried over MgS04. The solvent is evaporated leaving the title compound as an oil, which is used without further purification. Yield: 6.61 g (crude); LC (method 2): tR = 1 .30 min; Mass spectrum (EST): m/z = 260[M+Na]+.
With the rapid development of chemical substances, we look forward to future research findings about 2919-23-5.
