Procedure

2.5 Grams of 2-ethylamino-4,6-dichloro-5-methylthio-pyrimidine, 9 g of the mixture of 2-ethylamino-4,6-dichloro-5-methylthio-pyrimidine and 4-ethylamino-2,6-dichloro-5-methylthio-pyrimidine obtained in the first stage of Example 1, 165 g of methanol and 16 g of ammonia are introduced into a 500 ml autoclave. The mixture is heated for 2 hours at 120° C., then cooled. The solution obtained is concentrated under reduced pressure and the residue is washed with water. 8.2 Grams of a mixture melting at 76° C. are thus obtained. The analysis of the mixture by gas chromatography and mass spectrometry shows that it contains 56.6% of 2-amino-6-chloro-4-ethylamino-5-methylthio-pyrimidine, 37.8% of 4-amino-2-ethylamino-6-chloro-5-methylthio-pyrimidine and 5.6% of 6-amino-4-ethylamino-2-chloro-5-methylthio-pyrimidine.
