| Product | HCID 178451811 | HCID 178451811 | 59% |
Reaction Steps
A mixture of 1,1-dimethylethyl 4-[(5-bromo-3-cyano-2-fluorophenyl)carbonyl]-1-piperidinecarboxylate (1.35 g, 3.3 mmols) and hydrazine hydrate (0.21 ml, 6.9 mmols) in ethanol (30 mL) was heated at reflux overnight. After cooling, the solvent was evaporated and the residue was purified by flash chromatography eluting with pentane/ethyl acetate 4:1 v/v to give the title compound (0.78 g) as a yellow solid (59%).
