Reaction Steps
2-Anilino-4-methyl-6-(1-propynyl)pyrimidine (2.2 g) was dissolved in 100 ml of ethanol, and 2 ml of concentrated sulfuric acid was added thereto and stirred for 1 hour at room temperature. The crystals deposited were filtered, and dried to afford 2.4 g of 2-anilino-4-methyl-6-(1-propynyl)pyrimidine sulfate (yield 75%). Melting point: 192°-195° C.
