Reaction Steps

Under argon gas, 7-[4-(4-chlorobenzoyl)benzyl]-5-methyl-2-methylthio-7H-pyrrolo[2,3-d]pyrimidin-4(3H)-one (2.46 g) was dissolved in anhydrous DME (72.5 ml)anhydrous DMF (72.5 ml) and, under ice-cooling, 60% sodium hydride-oil (255 mg) was added in two installments. The mixture was stirred for 30 minutes sand ethyl iodide (1.09 g) was added. Then, the mixture was further stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate, washed with saturated aqueous NaCl solution, and dried over anhydrous sodium sulfate. The solvent was then distilled off under reduced pressure and the residue was purified by flash column chromatography [silica gel; dichloromethane→methanol: dichloromethane (1:49)] to provide the title compound (1.04 g).
