Reaction Steps
Into a mixture of 0.040 g of sodium hydride (60% in oil) and 2 ml of tetrahydrofuran, a solution of 0.096 g of 3,5-dimethylpyrazole in 3 ml of tetrahydrofuran was added dropwise. The mixture was added to a solution of 0.32 g of 5,7-dichloro-6-(2,4,6-trifluorophenyl)imidazo[1,2-a]pyrimidine in 5 ml of tetrahydrofuran under ice-cooling. To the reaction mixture, chloroform and aqueous citric acid solution were added. The separated organic layer was washed with water, dried over sodium sulfate and concentrated. The residue was subjected to silica gel column chromatography to give 0.18 g of 5-(3,5-dimethylpyrazol-1-yl)-6-(2,4,6-trifluorophenyl)-7-chloroimidazo[1,2-a]pyrimidine.
