Cesium carbonate → HCID 58166473, compound

Participants

Reaction Steps

To DMF (3 mL) were added N′-(5-fluoro-2-hydroxypyrimidin-4-yl)-N,N-dimethylformamidine (100 mg, 0.54 mmol), cesium carbonate (196 mg, 0.6 mmol), and chloromethyl pivalate (90 mg, 0.6 mmol), and the mixture was shaken at room temperature for 16 h. The mixture was partitioned between EtOAc and H2O. The organic phase was dried over MgSO4, filtered, and evaporated. To the resultant crude oil Et2O (3.5 mL) was added and a precipitate formed which was collected by filtration. The title compound was isolated as a white solid (37 mg, 23%): mp 193-194° C.; 1H NMR (300 MHz, DMSO-d6) δ 8.67 (s, 1H), 8.07 (d, J=6.3 Hz, 1H), 5.60 (s, 2H), 3.22 (s, 3H), 3.09 (s, 3H), 1.11 (s, 9H); ESIMS m/z 299 ([M+H]+).
