Reaction Steps

To a solution of 5-bromo-2,4-dichloropyrimidine (1.29 g, 5.66 mmol) in EtOH (15 ml) at room temperature was added a solution of 5-methyl-1H-pyrazol-3-amine (549 mg, 5.66 mmol) in EtOH (3 ml) and triethylamine (628 mg, 6.22 mmol) and the reaction mixture was stirred at room temperature overnight. The suspension was filtered and washed with water and dried to give the desired product as a white solid (1.27 g, 78%). NMR (CDCl3) 2.24 (s, 3H), 6.24 (s, 1H), 8.41 (s, 1H), 9.29 (s, 1H), 12.32 (s, 1H).
