実験手順
A solution of 2 mmole of 4-amino-4-difluoromethylbutyric acid in 15 ml of dichloromethane is treated with 2 mmole of thionyl chloride at 25° C. for one hour after which 20 ml of ethanol is added. The solution is stirred at 25° C. for one hour, washed with water, dried and concentrated to afford 4-amino-4-difluoromethylbutyric acid ethyl ester.
