Participants

Reaction Steps

An amount of 820 mg (2.96 mmol) of ethyl 4-(2-chlorophenyl)-2-methylpyrimidine-5-carboxylate and 633 mg (3.55 mmol) of N-bromosuccinimide were dissolved in 18 ml of carbon tetrachloride and heated with stirring to boiling. At the heat of boiling, in portions, 49 mg (0.29 mmol) of 2,2′-azobis-2-methylpropanenitrile were added over 5 hours, followed by refluxing for a further hour. After cooling to room temperature, the reaction solution was filtered and the mother liquor was freed from the solvent under reduced pressure. The desired product was isolated by chromatographic purification.
