Reaction Steps

A 20 mL vial was charged with 5-fluoro-4-hydrazinyl-2-(3-methoxybenzyloxy)-pyrimidine (74.7 mg, 0.283 mmol), EtOH (2 mL), thiophene-2-carbaldehyde (26 μL, 0.284 mmol) and 1 M HCl in Et2O (14 μL, 0.014 mmol) and heated at 50° C. on shaker. After 90 minutes, the reaction was cooled to room temperature concentrated on high vacuum to provide the title compound (77.8 mg, 77%) as a yellow solid: mp 136-139° C.; 1H NMR (300 MHz, DMSO-d6) δ 11.46 (bs, 1H), 8.50 (bs, 1H), 8.16 (d, J=3.6 Hz, 1H), 7.64 (d, J=5.0 Hz, 1H), 7.41 (d, J=3.4 Hz, 1H), 7.28 (t, J=8.0 Hz, 1H), 7.12 (dd, J=3.8, 4.8 Hz, 1H), 7.04 (m, 2H), 6.88 (dd, J=2.4, 8.3 Hz, 1H), 5.27 (s, 2H), 3.73 (s, 3H); MS (ESI) m/z 359.2 (M+H)+, 357.2 (M−H)−.
