In 3 ml of DMF was dissolved 300 mg (1.4 mmol) of 2,4-dichloro-7-methylthieno [3,2-d]pyrimidine, and after 204 mg (2.1 mmol) of cyclohexylamine was added to the resulting solution, the mixture was stirred for 3 hours. Water was added to the reaction mixture, and crystals thus precipitated were filtered to give 379 mg (yield: 98.2%) of the title compound.
