Reaction Steps

A solution of N-[1-{3-(1-tert-butoxycarbonyl-4-piperidyl)propionyl}-3-piperidylcarbonyl]-β-alanine methyl ester (2.03 g) in methanol (10 ml) and water (10 ml) was added lithium hydroxide (0.56 g) under stirring at 0° C. After stirring at ambient temperature for 1 hour, the mixture was acidified with 5% KHSO4 aqueous solution and extracted with ethyl acetate. The extract was washed with water, brine and dried over MgSO4, and evaporated in vacuo to give N-[1-{3-(1-tert-butoxycarbonyl-4-piperidyl)propionyl}-3-piperidylcarbonyl]-β-alanine as an oil (1.62 g).
