実験手順

2,4,5-Triamino-6-benzyloxypyrimidine (Pfleiderer et al., Chem. Ber., 94, 12-18 (1961)) (1.85 g, 8 mmol) and 1,1'-carbonyldiimidazole (1.30 g, 8 mmol) were dissolved in anhydrous N,N-dimethylformamide (5 mL) under argon. The solution was stirred at room temperature overnight and was mixed with water (200 mL) to precipitate a white solid. The solid was collected by filtration, and dissolved in 250 mL of aqueous 2N NaOH solution. Undissolved material was removed by filtration, and the filtrate was neutralized with glacial acetic acid to precipitate a white solid. The solid was collected by filtration, was washed with water, and was recrystallized from 50% aqueous ethanol to afford analytically pure 1c: yield, 1.63 g (79%); mp 256°-257° C. dec.; UV (pH 1) λmax 243 nm (ε=0.717×104), 306 (1.499×104); (pH 6.9) 243 (0.915×104), 290 (1.108×104); (pH 13) 249 (sh) (0.443×104), 293 (1.368×104); 1H NMR δ5.41 (s, 2H, ArCH2), 6.13 (s, 2H, NH2, exchange with D2O), 7.33-7.51 (m, 5H, ArH), 10.46 (s, 1H, exchanges with D2O), 11.04 (s, 1H, exchanges with D2 O); MS (EI) Calcd. m/z for C12H11N5O2 : 257.0912.
