Reaction Steps

In a 25 mL sealable tube were combined 4-{2-amino-6-[(1-methylethyl)amino]-4-pyrimidinyl}-2-fluorobenzonitrile (0.21 g, 0.54 mmol), hydrazine monohydrate (1.06 mL, 21.6 mmol), and EtOH (10 mL). The tube was sealed and the reaction mixture was stirred overnight at 95° C. The mixture was concentrated and to the resulting solid was added to EtOH (2 mL) followed by hexanes (15 mL). The mixture was sonicated and filtered. The solid was washed with hexanes to afford the title compound (167 mg, 99%) as an off-white solid. LC-MS (ES) m/z=284 [M+H]+. 1H NMR (400 MHz, DMSO-d6): δ 1.15 (d, J=6.6 Hz, 6H), 4.12 (bs, 1H), 5.36 (s, 2H), 5.94 (s, 2H), 6.24 (s, 1H), 6.71 (d, J=7.6 Hz, 1H), 7.40 (d, J=8.6 Hz, 1H), 7.69 (d, J=8.3 Hz, 1H), 7.82 (s, 1H), 11.50 (bs, 1H).
