実験手順
To a solution of 3-methyl-7-((5-methylpyridin-2-yl)methyl)-8-(3-(trifluoromethoxy)benzyl)-1H-purine-2,6(3H,7H)-dione (30 mg, 0.067 mmol, intermediate 51) in DMF (3 mL) was added 3-hydroxybutyl-4-methylbenzenesulfonate (24.68 mg, 0.10 mmol), followed by potassium carbonate (27.93 mg, 0.20 mmol). The reaction was stirred at 70° C. for 4 h. The mixture was partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over sodium sulfate, filtered and concentrated to give crude product, which was purified by preparative HPLC to give 1-(3-hydroxybutyl)-3-methyl-7-((5-methylpyridin-2-yl)methyl)-8-(3-(trifluoromethoxy)benzyl)-1H-purine-2,6(3H,7H)-dione (9 mg, 25.8%) as white solid. 1H-NMR (CD3OD) δ 8.216(s,1H), 7.491-7.467(d,1H), 7.312-7.272(m,1H), 7.154-6.995(m,4H), 5.688(s,2H), 4.305(s,2H), 4.143-4.011(m,2H), 3.772-3.440(m,1H), 3.585(s, 3H), 2.283(s,3H), 1.761-1.703(m,2H), 1.194-1.179(d,3H). LCMS retention time 2.569 min; LCMS MH+ 518.
