Reaction Steps

To a solution of tert-butyl 4-[3-(4-chlorophenyl)prop-2-ynoyl]piperidine-1-carboxylate (5.28 g, 15.18 mmol) in ethanol (160 mL) was added hydrazine (0.953 mL, 30.4 mmol) and triethylamine (4.23 mL, 30 4 mmol). The mixture was heated at 75° C. for 3 h. The solvent was evaporated under reduced pressure, and dried under vacuum to give INTERMEDIATE 1. LC-MS m/z 362.19 [M+H]+, 306.14 [M−56+H]+.
