Procedure

To a solution of 175 mg (0.5 mmol) of 2-(methylsulfonyl)-N-(1-methyl-1H-tetrazol-5-yl)-4-(trifluoromethyl)benzamide in 4 ml of THF (abs.) under protective gas at 0° C. are added 14 mg (0.55 mmol) of sodium hydride (95%). After stirring for 10 min, 46 μl (0.6 mmol) of methyl chloroformate are added at 0° C. The reaction mixture is stirred at RT for 1 h. Subsequently, the reaction mixture is adjusted to pH 7 with an aqueous sat. sodium hydrogencarbonate solution, and 10 ml of water are added. Then the mixture is extracted with ethyl acetate. The organic phase is dried over sodium sulfate, filtered and concentrated. Yield: 231 mg (57%)
