実験手順

A solution of 3-(4-Chloro-benzoyl)-azetidine-1-carboxylic acid tert-butyl ester (62.5 g, 210 mmol) in ethanol (1000 ml) cooled to 10° C. is treated with sodium borohydride (9.5 g, 250 mmol). The reaction mixture is allowed to warm to room temperature and stirred for 2 hours. The reaction mixture is added to water and the precipitate collected by filtration, and dried under vacuum to afford 3-[(4-Chloro-phenyl)-hydroxy-methyl]-azetidine-1-carboxylic acid tert-butyl ester. Mpt 123-125° C.
