Benzoyl chloride → Benzoic Acid 4-(dimethylamino-methyleneamino)-5-fluoropyrimidin-2-yl Ester

Participants

Reaction Steps

To a suspension of N′-(5-fluoro-2-hydroxypyrimidin-4-yl)-N,N-dimethylformamidine (0.10 g, 0.54 mmol) in pyridine (2 mL) was added benzoyl chloride (0.084 g, 0.60 mmol), and the mixture was agitated on an orbital shaker for 16 h at RT. The reaction mixture was partitioned between EtOAc and saturated aq NaHCO3, and the organic phase was dried over solid MgSO4, filtered, and evaporated to give the title compound (0.147 g 94%) as a white solid: mp 136-138° C.; 1H NMR (300 MHz, CDCl3) δ 8.69 (s, 1H), 8.27 (d, J=2.4 Hz, 2H), 8.25-8.20 (m, 2H), 7.69-7.63 (m, 1H), 7.56-7.49 (m, 2H), 3.23 (s, 3H), 3.20 (s, 3H); HPLC-MS (ESI) m/z 289 (M+H)+.
