Procedure
A solution of 0.43 g (3.73 mmoles) of maleic acid in 10 ml of methanol was added to a solution of 1.0 g (3.73 mmoles) of 4-methylamino-2-(4-phenylpiperidino)pyrimidine in 10 ml of methanol, and the mixture was stirred at room temperature for 1 hour. The mixed solution was concentrated under reduced pressure and washed with ether to give 1.25 g (yield 87 %) of the desired product.
