Procedure
A mixture of 4,6-dichloropyrimidine (3.0 g), 4-aminophenol (2.2 g) and triethylamine (6 ml) in ethanol.(50 ml) was refluxed for 2 hours. The product so obtained was recrystallised from a mixture of ethyl acetate and hexane to give 6-chloro-4-(4'-hydroxyanilino)pyrimidine in 76% yield, m.p. 241-244° C.;
