Reaction Steps

4-(2-Cyano-phenyl)-piperidine-1-carboxylic acid tert-butyl ester (0.15 g) was dissolved in a solution of hydrogen chloride in dioxane (4 M, 2 mL) and the mixture stirred for 1 hour. The solvent was evaporated under vacuum, and the resulting solid triturated from diethyl ether to give the title compound as a grey solid (0.1 g). LCMS m/z 187.2[M+H]+.
