Procedure

Crude 2-{[2-(3-methoxy-4-methyl-phenyl)-ethylamino]-methyl}-N-(4-phenyl-butyl)-benzamide (derived via Procedure C from 200 mg resin) is dissolved in 3 mL of dichloromethane and treated with 0.5 mL of 1 M of boron tribromide in dichloromethane for 16 h. Methanol (3 mL) is carefully added and the volatiles are removed. The crude residue is purified via semi-preparative HPLC to give 2-{[2-(3-hydroxy-4-methyl-phenyl)-ethylamino]-methyl}-N-(4-phenyl-butyl)-benzamide (28 mg). MS: m/z 417 (m+H).
