Reaktionsschritte

To a 10 ml vial was added 4-(1-methyl-1-{[3-(trifluoromethyl)phenyl]sulfonyl}ethyl)piperidine (70.8 mg, 0.211 mmol), 2-(methylsulfonyl)-4-(trifluoromethoxy)benzoic acid (50 mg, 0.176 mmol), Bop reagent (93 mg, 0.211 mmol), diisopropylethyl amine (0.062 ml, 0.352 mmol) and 2 ml dimethylformamide. The resulting solution was stirred at room temperature for 10 minutes. 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 with HPLC eluted with water/acetonitrile gradient solvent. Desired fraction was collected and lyophilized to give to give title compound as fluffy white solid.
