실험 절차

In an argon gas stream, 60% sodium hydride-oil (220 mg) was suspended in anhydrous DMF (5 ml) and a powder of 4-methoxy-5-methyl-2-methylthio-7H-pyrrolo[2,3-d]pyrimidine (1.05 g) was added in small portions with ice-cooling and stirring. After completion of addition, the mixture was stirred for 30 minutes and then a solution of 4-(4-chlorobenzoyl)benzyl bromide (1.63 g) in DMF (5 ml) was added. Then, at room temperature, the mixture was stirred for 2 hours. To this reaction mixture was added water (50 ml) and the resulting precipitate was collected by filtration, rinsed with water, dried, and purified by flash column chromatography (silica gel; hexane: ethyl acetate=9:1) to provide the title compound (1.19 g). 1H-NMR (CDCl3) δ: 2.33(3H,d,J=1.2Hz), 2.60(3H,s), 4.08(3H,s), 5.36(2H,s), 6.57(1H,d,J=1.2Hz), 7.28(2H,d,J=8.6Hz), 7.44(2H,d,J=8.6Hz), 7.70(2H,d,J=8.6Hz), 7.72(2H,d,J=8.6Hz).
