実験手順
A mixture of 4-chloro-6-(3'-methylanilino)pyrimidine (9.56 g) and 3-aminophenol (5.22 g) was stirred and heated at 140° C. for 3 hours. The product so obtained was dissolved in methylene chloride and a few drops of methanol, and chromatographed on silica using a mixture of methylene chloride and methanol, increasing in polarity from pure methylene chloride to a 19:1 mixture of methylene chloride and methanol as eluent. The product so obtained was recrystallised from a mixture of ethyl acetate and hexane to give 4-(3'-hydroxyanilino)-6-(3'-methylanilino)pyrimidine in 39% yield, m.p. 188°-189° C.;
