Procedure

A mixture of 2-[2-Benzyloxy-4-(4-benzyl-piperazin-1-yl)-5-methoxy-phenyl]-propan-2-ol (2.01 g, 4.5 mmol) 10% Pd/C (0.28 g) in EtOH (60 mL) was hydrogenated at 50 psi at room temperature for 12 hours. The reaction mixture was filtered to remove the catalyst, and the filtrate was concentrated under reduced pressure to yield 1.1 g (92%) of 2-(1-Hydroxy-1-methyl-ethyl)-4-methoxy-5-piperazin-1-yl-phenol.
