실험 절차
A mixture of 4-methyl-2-(4-trifluoromethylphenyl)pyrimidine (3 g) and bromine (2.11 g) in 20 ml of acetic acid was warmed to 80° C. for 1 hour, and then allowed to cool to room temperature. Ether (10 ml) was added., and the precipitate filtered off and washed with ether, giving 3.3 g of 4-bromomethyl-2-(4-trifluoromethylphenyl)pyrimidine, m.p. 125° C.
