実験手順

To a cooled (ice-water bath) and stirred mixture of ethanolamine (0.066 g, 1.08 mmol), triethylamine (0.11 ml, 0.76 mmol) and THF (2 ml) was added drop wise a solution of 3-{4-[4-trifluoromethyl-6-(4-trifluoromethyl-phenyl)-pyrimidin-2-yl]-pyridin-2-yl}-benzenesulfonyl chloride hydrochloride (example I.1) (0.21 g, 0.36 mmol) in THF (3 ml). The mixture was allowed to stir at room temperature for 16 h. Purification of the reaction mixture by flash chromatography on silica gel (ethyl acetate/hexane) and crystallization (diethyl ether/hexane) yielded the title compound as a white solid (0.156 g, 76%). MS (ISP) 569.2 [(M+H)+]; mp 192.5° C.
