Participants

Reaction Steps

A solution of (4-tert-butyl-benzyl)-[2-(3-ethynyl-phenyl)-ethyl]-carbamic acid tert-butyl ester (149 mg, 0.381 mmol) in methanol (12 ml) was stirred at RT under an atmosphere of hydrogen in the presence of a catalytic amount of palladium on charcoal (5%) for 2 days. The reaction mixture was then filtered and evaporated and the remaining residue was purified by chromatography (heptane/EtOAc 100:0 to 95:5) to obtain the title compound as a colorless oil (73 mg, 48%).
