Analyzing the synthesis route of (1S,2S)-2-Aminocyclopentanol hydrochloride

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,68327-04-8, its application will become more common.

Adding a certain compound to certain chemical reactions, such as: 68327-04-8, (1S,2S)-2-Aminocyclopentanol hydrochloride, 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, 68327-04-8, blongs to alcohols-buliding-blocks compound. HPLC of Formula: C5H12ClNO

To a mixture of 2- (benzoyloxy) -5-bromo-3-chloro-4- methylbenzoic acid (13.2 g) , (IS, 2S) -2-aminocyclopentanol hydrochloride (4.93 g) , triethylamine (16.5 mL) , and DMF (250 mL) was added HATU (15.0 g) at 0C, and the mixture was stirred at room temperature for 4 hr. To the reaction mixture were added ethyl acetate and water at 0C. The organic layer was separated, and the aqueous layer was extracted with ethyl acetate. The combined organic layer was washed with water and brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (3.36 g).MS: [M+H]+452.0,’454.0

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,68327-04-8, its application will become more common.
