Hydrochloric Acid → HCID 20489855, compound

Participants

Reaction Steps

A solution of 15.2 g of 3,4-dimethoxybenzoyl chloride in 40 ml of chloroform is added dropwise to a solution of 15.0 g 2-phenyl-5-chloromethyloxazolidine in a mixture of 200 ml of chloroform and 6 ml of pyridine at a temperture of -40° C. under agitation. This solution is then heated to room temperature. After a reaction period of 14 hours, 20 ml of concentrated hydrochloric acid are added, the phases are thoroughly mixed for a period of 10 minutes and then are separated. The separated aqueous phase is diluted with water to twice its volume and then is saturated with sodium chloride and extracted with chloroform. After drying the chloroform-extract and evaporating the solvent, 15.0 g of N-(3,4-dimethoxybenzoyl)-3-chloro-1-aminopropan-2-ol is obtained as an oil which can be further reacted without any purification. After crystallization from ethanol/toluene the compound exhibits a melting point of 104°-106° C.
