実験手順
1.70 g (3.53 mMol) N-(4-amino-2-methyl-6-(((1-methylethyl)amino)carbonyl)phenyl)-1-(3-chloro-2-pyridinyl)-3-(trifluoromethyl)-1H-pyrazole-5-carboxamide (known from WO 03/016284) and 41 mg (0.18 mmol) benzyltriethylammonium chloride in 35 mL conc. HCl and 35 mL toluene are vigorously stirred at 60° C. Then 0.58 mL (7 mmol) crotonaldehyde is added and the reaction mixture is stirred under reflux during 1 hour. The mixture is then cooled to ambient temperature, diluted with 10 mL ethyl acetate/tetrahydrofuran (1:1, v/v) and neutralised with an aqueous solution of concentrated ammonia. The organic phase is extracted and washed once with brine, then dried on Na2SO4, filtrated and evaporated. After column chromatography purification on silica gel with dichloromethane/tetrahydrofuran (3:1) as eluents, the compound is recrystallised from tetrahydrofuran/hexane to afford a colourless solid; LC/MS:531/533 (M+H)+, m.p.: >240° C.
