Benzoyl Peroxide → 5-Bromo-2-(bromomethyl)pyrimidine

Participants

Reaction Steps

A mixture of 5-bromo-2-methylpyrimidine (100 mg, 0.58 mmol), NBS (103 mg, 0.58 mmol), dibenzoyl peroxide (10 mg, 0.04 mmol) in tetrachloromethane (10 mL) was refluxed for 36 h. The solvent was removed in vacuo and the residue was purified by column chromatography on silica gel (ethyl acetate in petroleum ether, 1% v/v) to give 5-Bromo-2-(bromomethyl)pyrimidine (70 mg, 48%) as a white solid. 1HNMR (400 MHz, CDCl3) δ 4.49 (s, 2H), 8.72 (s, 2H).
