Acetyl chloride → N-[5-fluoro-2-(thiophen-2-ylmethoxy)pyrimidin-4-yl]acetamide

Participants

Reaction Steps

In a 2 dram screw cap vial, a solution of 5-fluoro-2-(thiophen-2-ylmethoxy)-pyrimidin-4-ylamine (0.10 g, 0.4 mmol) in CH2Cl2 was treated with acetyl chloride (0.032 g, 0.4 mmol,) and PS-NMM (0.42 g, 0.8 mmol), a resin-bound equivalent of N-methyl morpholine (NMM). The mixture was shaken at RT for 12 h. The reaction mixture was filtered and the solvent evaporated to yield 0.084 g (75%) of the title compound as white solid: mp 134-136° C.; 1H NMR (300 MHz, CDCl3) δ 8.24 (d, J=2.6 Hz, 1H), 7.86 (bs, 1H), 7.31 (m, 1H), 7.23 (m, 1H), 7.00 (m, 1H), 5.54 (s, 2H), 2.58 (s, 3H); MS (ESI) m/z 268 (M+H)+.
