Methyl iodide → HCID 18919017, compound

Participants

Reaction Steps

Under argon gas, 7-[4-(4-chlorobenzoyl)benzyl]-2-methylthio-7H-pyrrolo[2,3-d]pyrimidin-4(3H)-one (82 mg) was dissolved in anhydrous DME (10 ml)-anhydrous DMF (4 ml). Then, 60% sodium hydride-oil (9.6 mg) was added with ice-cooling and, after 30 minutes of agitation, methyl iodide (34 mg) was added. Then, at room temperature, the mixture was stirred for 2.5 hours. This reaction mixture was diluted with ethyl acetate, washed with saturated aqueous NaCl solution, and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure and the residue was purified by flash column chromatography (hexane: ethyl acetate=4:1) to provide the title compound (30 mg). 1H-NMR (CDCl3) δ: 2.58(3H,s), 3.60(3H,s), 5.37(2H,s), 6.67(1H,d,J=3.4Hz), 6.75(1H,d,J=3.4Hz), 7.30(2H,d,J=8.OHz), 7.45(2H,d,J=8.6Hz), 7.73(2H,d,J=8.6Hz), 7.74(2H,d,J=8.OHz).
