実験手順

To sodium hydride in mineral oil (60%, 0.007 g, 0.33 mmol) was added tetrahydrofuran (1.8 mL) and the suspension was cooled to 0° C. Ethyl 2-oxopyrrolidine-3-carboxylate (0.044 g, 0.28 mmol) was added and the solution was stirred for 15 minutes. N-{3-[2-(bromomethyl)-1,3-thiazol-5-yl]-5-methylphenyl}-4-(trifluoromethyl)pyrimidin-2-amine (0.100 g, 0.23 mmol) was dissolved in tetrahydrofuran (1.8 mL) and then added to the flask. The reaction was allowed to warm to room temperature overnight. The reaction was diluted with ethyl acetate, washed carefully with water, dried over magnesium sulfate, filtered and concentrated. The solid was purified by silica gel chromatography to yield ethyl 3-{[5-(3-methyl-5-{[4-(trifluoromethyl)-pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]methyl}-2-oxopyrrolidine-3-carboxylate (0.03 g, 27% yield).
