Procedure

100 g (0.322 mole) of 4,6-dichloro-2-(3-isopropoxypropylamino)-5-methylthio-pyrimidine are dissolved in 400 ml of methanol and the solution is heated at 100° C. with 500 ml of ammonia in an autoclave for 3 hours. The undissolved residue is filtered off. After the methanol phase has been concentrated, the residue which remains is taken up in methylene chloride, the mixture is washed with water and the resulting organic phase is dried. After removal of the solvent, the resulting oil is stirred with petroleum ether. The crystals thereby obtained are filtered off with suction. 81 g (87% of theory) of the desired pyrimidine, melting point: 76° C., are obtained.
