実験手順
A solution of 4-cyano-5-(p-tolyl)pyrimidine (1.2 g, 6 mmol), N-bromosuccinimide (1.15 g, 6 mmol) and benzoyl peroxide (catalytic amount) in carbon tetrachloride (50 ml) was refluxed under light radiation for 1 hour. After cooling, insoluble materials were removed and the filtrate was concentrated to dryness. Recrystallization from ether-isopropyl ether afforded colorless powders (1 g, 59%), m.p. 114°-116° C.
