Sodium hydride → HCID 86596304, compound

Participants

Reaction Steps

Sodium hydride (60% dispersion, 0.30 g, 0.75 mmol) was added to a solution of 2,4-dichloropyrimidine (0.75 g, 0.50 mmol) and (4-methoxyphenyl)-carbamic acid pyridin-3-ylmethyl ester (1.3 g, 0.50 mmol) in DMF (5 mL). The mixture was allowed to stir at room temperature for 2 h. The resulting solution was diluted with sat. aqueous ammonium chloride and ethyl acetate. The organic phase was separated and washed with brine, dried over anhydrous magnesium sulfate, filtered, and concentrated to afford a colorless oil. This oil was purified via column chromatography on silica gel (gradient elution with 0-5% methanol-dichloro-methane) to afford (2-chloropyrimidin-4-yl)-(4-methoxyphenyl)carbamic acid pyridin-3-ylmethyl ester as a tan solid. MS (MH+) 371; Calculated 370.8 for C18H15ClN4O3.
