Procedure

To a solution of 2,4-diamino-5-(2-chlorophenyl)-6-methyl pyrimidine (11.84 g) (Example 22) in concentrated H2SO4 (100 ml), was added potassium nitrate (5.1 g). After stirring at room temperature for 90 minutes, the solution was poured onto ice and basified with 10N NaOH. The product was extracted with ethyl acetate, bulked, dried (MgSO4) and evaporated, 13.9 g, 236°-240° C.
