Sodium hydride → HCID 21912078, compound

Participants

Reaction Steps

To a solution of mesitylacetonitrile (0.900 g, 5.65 mmol) in 8 ml dry THF was added sodium hydride (60% in oil, 0.250 g, 6.21 mmol) and the mixture was stirred at room temperature for 40 minutes. 2,5-Dimethyl-4,6-dichloropyrimidine (1.000 g, 5.65 mmol) was added and the resulting mixture was heated at reflux for 5 hours. The mixture was quenched with water and extracted with ethyl acetate. The organic layer was dried and concentrated to give 1.800 g of a yellow oil. The oil residue was purified through silica gel column chromatography using 10% ethyl acetate in hexane as eluent to give 0.986 g (58.3%) of the title compound as a white solid, mp 100-102° C. 1H NMR (CDCl3) δ 6.86 (s, 2H), 5.60 (s, 1H), 2.69 (s, 3H), 2.25 (s, 3H), 2.18 (s, 6H), 1.92 (s, 3H) ppm.
