実験手順
1-(2-Hydroxyethyl)imidazolidin-2-one (0.6 g, 4.6 mmol) was taken up in anhydrous THF (5 mL) and added dropwise to a reaction flask containing a suspension of sodium hydride (0.147 g (60% in oil), 3.68mmol) in anhydrous THF (10 mL) at 0° C. The ice bath was removed and the reaction allowed to warm up to room temperature over a 2 h period. 4-(benzo[b]thiophen-2-yl)-5-bromo-2-chloropyrimidine (0.3 g, 9.2 mmol), dissolved in THF was added dropwise. The reaction was stirred overnight. The reaction was then diluted with ethyl acetate and saturated sodium bicarbonate. The organic layer was then washed with water and brine. The organic portion was dried with sodium sulfate and then purified by flash chromatography on silica gel using a gradient of 0 to 10% methanol in dichloromethane to give a white solid. Yield=0.085 g. MS (M+H)+ 420.
