実験手順

Using an analogous reaction procedure to that described in Example 6, 6-chloro-4-(4'-hydroxyanilino)pyrimidine (3.2 g) was reacted with 3-methylaniline (5 ml). The product so obtained was triturated under methylene chloride. The solid so obtained was filtered off and extracted with hot water. On cooling a solid precipitated from the aqueous solution. The solid was extracted from the aqueous solution with ethyl acetate, washed with water and with brine, dried (MgSO4) and recrystallised from a mixture of ethyl acetate and hexane to give 4-(4'-hydroxyanilino)-6-(3'-methylanilino)pyrimidine (0.15 g), m.p. 242°-245° C.;
