Yield: 0.5 g
Reaction Conditions:
for 3 h;Reflux;Inert atmosphere;
Steps:
11.e e) l,3,9-Trimethyl-lH-purine-2,6(3H,9H)-dione (10)
A mixture of 5-amino-l,3-dimethyl-6-methylamino-pyrimidine-2,4(lH,3H)-dione (9) (1.5 g) and formic acid (10 mL) was refluxed for 3 h under nitrogen atmosphere. An excess of formic acid was evaporated under reduce pressure. The residue was extracted with CH2C12, washed with aq. Na2C03, dried over Na2S04 and evaporated to dryness. The residue was purified by column chromatography (eluent CH2C12 : MeOH, 10: 1) to give the title compound (0.5 g) as a white solid. NMR (400 MHz, DMSO~d6) δ (ppm): 3.22, 3.68 and 3.93 (all s, all 3H), 7.66 (s, 1 H). MS (EI) mlz: 195 |M+2]+
