Reaction Steps

The title compound was prepared according to the general procedure as described in method A for the preparation of phosphate derivatives by coupling N-[4-(3,4-dichlorophenyl)-1,3-thiazol-2-yl]-2-(1,3-dimethyl-2,6-dioxo-1,2,3,6-tetrahydro-7H-purin-7-yl)acetamide (150 mg, 0.322 mmol) with freshly prepared di-tert-butyl iodomethyl phosphate (Intermediate 2) (395.16 mg, 1.129 mmol) in the presence of sodium hydride (60% dispersion in mineral oil, 20 mg, 0.483 mmol) in dry DMF (2 ml) with to yield 135 mg of pure product as an off-white solid. 1H NMR (300 MHz, CDCl3): δ 1.48 (br s, 18H), 3.35 (s, 3H), 3.47 (s, 2H), 3.62 (s, 3H), 5.71 (s, 2H), 6.36 (br s, 2H), 7.42-7.50 (m, 1H), 7.60-7.72 (m, 1H), 8.02 (s, 1H).
