To a 10 ml vial was added 4-(1-methyl-1-{[3-(trifluoromethyl)phenyl]sulfonyl}ethyl)piperidine (33 mg, 0.098 mmol), benzoic acid (10 mg, 0.082 mmol), Bop reagent (43.5 mg, 0.098 mmol), diisopropylethyl amine (0.029 ml, 0.164 mmol) and 2 ml dimethylformamide. The resulting solution was stirred at room temperature for 10 minutes. LC-Mass showed clean desired product. The reaction mixture was diluted with 1 ml dimethyl sulfoxide, 1 ml water and 0.03 ml of trifluoroacetic acid. This mixture was loaded on a reverse phase column and purified on HPLC eluted with water/acetonitrile gradient solvent. Desired fraction was collected and lyophilized to give the title compound as a fluffy white solid.
