Procedure
A mixture of 5.0 g (0.016 mole) of 5-[4-(4-cyanophenyl)-1-piperazinyl]-6-methyl-2,4-pyrimidinediamine, 30 ml of 95% ethanol and 30 ml of sulfuric acid was heated under reflux at 130° C. for four hours and cooled. The solution was poured into 400 g of ice. The solid was collected, washed first with 5N aqueous sodium carbonate solution and then with 50 ml of water. Recrystallization from N,N-dimethylformamide gave 1.72 g of the product as an off-white solid, mp 281°-285° C.
