Chloroacetyl chloride → HCID 69060917, compound

Participants

Reaction Steps

A solution of chloroacetyl chloride (268 mg, 2.38 mmol) in dry DCM (5 ml) was added dropwise over 10 minutes to a stirred solution of 2-anilino-4-(2-hydroxyethylaminomethyl)pyrimidine (Method 19; 582 mg, 2.38 mmol) and triethylamine (332 μl, 2.38 mmol) in dry DCM (20 ml) under nitrogen. The reaction mixture was then stirred for 20 hours at ambient temperature. The mixture was diluted with DCM and washed with water (×2), saturated brine, dried (Na2SO4) and the volatiles removed by evaporation. The residue was dissolved in dry THF (20 ml), sodium bromide (227 mg, 2.2 mmol) added and the mixture stirred at 0° C. under nitrogen sodium hydride (88 mg of a 60% dispersion in oil) was added in one portion and the reaction stirred at 0° C. for 10 minutes and then at ambient temperature for 72 hours. The volatiles were removed by evaporation and the residue partition between EtOAc and water. The layers were separated and the organic layer washed with water, saturated brine, dried (Na2SO4) and the solvent removed by evaporation. The residue was purified by chromatography eluting with EtOAc. The purified product was triturated with diethyl ether, collected by filtration, washed with diethyl ether and dried to give the title compound (438 mg, 70%) as a white solid.
