Procedure

To a solution of (2-{[(3,5-bis-trifluoromethyl-benzyl)-(2-methyl-2H-tetrazol-5-yl)-amino]-methyl}-4-trifluoromethyl-phenyl)-cyclohexyl-methanol (51 mg; 0.086 mmol) in methylene chloride (1.2 mL) was added N-bromosuccinimide (63 mg; 0.354 mmol) and triphenylphosphine (97 mg; 0.369 mmol). The reaction was stirred at room temperature for 16 hours. Reaction was directly purified over 4 g RediSep column (Teledyne Isco Inc., Lincoln Nebr.) (eluted with 10-45% ethyl acetate in heptane) to give 27 mg (48% yield) of the title compound as a colorless gum.
