Versuchsvorschrift

Under argon gas, 7-[4-(4-chlorobenzoyl)benzyl]-4-methoxy-5-methyl-2-methylthio-7H-pyrrolo[2,3-d]pyrimidine (0.671 g) was dissolved in dioxane (8 ml) followed by addition of 4,4'-thiobis(6-t-butyl-m-cresol) (7.2 mg). Then, 0.5N-hydrochloric acid (1.12 ml) was added and the mixture was stirred at 105° C. for 36 hours. Thereafter, 0.5 N-hydrochloric acid (1.12 ml) was added again and the mixture was further stirred at the same temperature as above for 24 hours. To this reaction mixture was added water (30 ml) and the resulting precipitate was collected by filtration and dried. The dried precipitate was purified by flash column chromatography (chloroform) to provide the title compound (0.312 g). 1H-NMR (DMSO-d6) 8: 2.24(3H,s), 2.51(3H,d,J=l.OHz), 5.33(2H,s), 6.83(1H,d,J=l.OHz), 7.43(2H,d,J=8.2Hz), 7.60(2H,d,J=8.6Hz), 7.71(2H,d,J=8.2Hz), 7.73(2H,d,J=8.6Hz), 12.01(1H,s).
