Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of benzyl 3-(4-acetamidopiperidin-1-yl)propanoate (3.81 g, 12.5 mmol) and Pd/C (10%, 0.20 g) in methanol (100 mL) was stirred under hydrogen atmosphere overnight. The solid was filtered and the filtrate was evaporated to give 3-(4-acetamidopiperidin-1-yl)propanoic acid (2.50 g). LCMS (+ESI) 215 (M+1). The solid was filtered the filtrate was evaporated

Conditions: temp:40.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A stirred mixture of 4-acetamidopiperidine (1.82 g, 12.8 mmol) and benzyl acrylate (2.57 g, 15.4 mmol) in acetonitrile (50 mL) was stirred overnight under nitrogen and at 40° C. for 1 h. The mixture was evaporated to dryness and the residue was purified by silica gel chromatograph eluting with a gradient of 0% to 30% dichloromethane/methanol/NH4OH (10:1:0.1) and dichloromethane to give benzyl 3-(4-acetamidopiperidin-1-yl)propanoate as an oil (3.81 g, 98%). The mixture was evaporated to dryness the residue was purified by silica gel chromatograph eluting with a gradient of 0% to 30% dichloromethane/methanol/NH4OH (10:1:0.1) and dichloromethane
