Procedure
tert-butyl (3S)-3-(cyclopropylmethylamino)pyrrolidine-1-carboxylate was prepared by a method similar to that described in preparation 1 using tert-butyl (3S)-3-aminopyrrolidine-1-carboxylate and cyclopropane carboxaldehyde except that the crude product was purified by chromatography on silica gel eluting with a solvent gradient of dichloromethane changing to dichloromethane:methanol:0.88 ammonia (90:10:1 by volume) to yield the title compound, 5.2 g (81%).
