Reaction Steps

A solution of (S)-1-(3-benzyloxy-propyl)-3-methyl-piperazin-2-one (9.07 g, 34.6 mmol) in methanol only heated for 14 h at 70° C. under a hydrogen atmosphere (7 bar) in the presence of palladium (10% on activated charcoal, 7.36 g). After cooling, insoluble material was removed by filtration and the filtrate evaporated to produce the title compound (5.90 g, 99%). Colorless oil, MS (ISP)=173.1 (M+H)+.
