Participants

Reaction Steps

N-(2-Amino-4,6-dichloro-5-pyrimidinyl)formamide (Example 3, 500 mg, 2.14 mmol) and ammonia (150 mL) was stirred in a Parr bomb at 50° C. for 18 hours. The ammonia was evaporated and the residual solid triturated with water (10 mL). The solid was dried to give the tile compound as red powder (400 mg, 89%), m.p.>300° C.; mass spectrum (CI/CH4): 190, 188 (M+1); 1H-NMR(DMSO-d6)δ: 9.05 and 8.60 (both br s, total 1, NHCHO), 8.1 and 7.8 (both br s, total 1, NHCHO), 6.80-6.20 (4 br s, total 4, 2 NH2).
