실험 절차

2-(2,4-Dichlorophenyl)-1-(4-hydroxyphenyl)-5-methyl-1H-imidazole-4-carboxylic piperidin-1-ylamide, from Ex 2, Step 1 (0.49 g, 1.20 mmol) was dissolved in dichloromethane (20 ml), cooled to 0° C. and triethylamine (0.67 ml, 4.8 mmol) added followed by 4,4,4-trifluorobutane-1-sulfonyl chloride (prepared as described in WO00/010968) (0.38 g, 1.80 mmol). The reaction mixture was stirred at room temperature for 3 hrs. TLC showed remaining starting material and another portion of triethylamine and 4,4,4-trifluorobutane-1-sulfonyl chloride was added and the reaction mixture stirred overnight. Water was added, the product extracted with dichloromethane, dried (Na2SO4), filtered and concentrated. Flash chromatography (hexane:EtOAc 1:3-EtOAc) followed by recrystallization (hexane:EtOAc) afforded 0.45 g (61%) of the title compound as a colorless solid.
