Procedure

3-ethyl-4-[(phenylmethyl)oxy]benzonitrile (Intermediate 112, 334 mg) was dissolved in 15 mL of EtOAc/EtOH (2/1) and 10% mol Pd/C (0.1 equiv) was added to the solution. The resulting mixture was stirred overnight at room temperature under hydrogen gas atmosphere. The reaction mixture was filtered under argon and the solvent was removed. The residue obtained was purified by chromatography on silica gel (Companion system, 40 g Si cartridge) using as eluent a gradient cyclohexane/ethyl acetate from 100:0 to 80:20. Evaporation afforded the title compound (148 mg) as a white solid.
