Reaction Steps

To a solution of methyl 4-(trifluoromethyl)pyrimidine-2-carboxylate (500 mg, 2.4 mmol) in EtOH (12 mL) was added hydrazine monohydrate (0.24 mL, 4.9 mmol). After 1 h, the reaction was concentrated to afford the desired product as a white solid (426 mg, 85%). 1H NMR (400 MHz, CDCl3) δ 9.22 (d, J=5.0 Hz, 1H), 9.05 (s, 1H), 7.83 (d, J=5.0 Hz, 1H), 4.25 (br s, 2H).
