68% | With ammonia In methanol at 140℃; for 0.666667 h; | A mixture of 4,6-dichloro-5-methylpyrimidine (available from Sigma-Aldrich No.595446) (5 g, 30.70 mmol) in ammonia (7 M solution in MeOH, 15 ml, 105 mmol) was left under stirring for 40 min in a sealed vial at 140 0C. Water (300 ml) and EtOAc (600 ml) were added to the resulting white suspension and the two layers were separated. The aqueous phase was extracted with EtOAc (3 x 600 ml). The collected organic phases were dried (Na2SO4), filtered and concentrated under reduced pressure to give the title compound D3 (3.10 g, 20.73 mmol, 68percent yield) as a white solid. UPLC: rt = 0.41 min, peaks observed: 144 (M+l, 100percent) and 146 (M+ 1, 33percent). C5H6ClN3 requires 143. 1H NMR (400 MHz, DMSO- d6) δ(ppm): 8.06 (s, 1 H), 7.09 (bs, 2 H), 2.07 (s, 3 H). |
