To a stirring solution of (2-chloro-3-trifluoromethyl-benzyl)-(2,2-diphenyl-ethyl)-{3-[3-(ethoxymethyl-1,2,3,4-tetrazol-5-ylmethyl)-phenoxy]-propyl}-amine (mixture of regioisomers, 125 mg, 0.19 mmol) in dichloromethane (11 ml) was added triethylsilane (116 mg, 1.08 mmol). The reaction mixture was treated with TFA (3 ml) and then stirred overnight. Solvent was removed and the residue was purified by preparative HPLC (YMC CombiPrep PDS, 75×30 mm, 25 mL/min, acetonitrile:water, UV detection at 254 nm) to afford 50 mg (44%) the title compound as a yellow oil. MS (ESI) 607.0(M+H+).
