Reaction Steps

To a solution of 1,1-dimethylethyl 4-[(3′-cyano-3-biphenylyl)methylidene]-1-piperidinecarboxylate (1.87 g, 4.99 mmol) in MeOH (499 mL) was added HCl (4.99 mL, 1N, 4.99 mmol) then was applied to H-cube hydrogenation apparatus until the reaction was complete per monitoring with LC-MS. The reaction mixture was concentrated to afford 1.40 g (67%) of the title compound. LC-MS m/z 381 (M+H)+.
