Versuchsvorschrift

5.309 g N-(3-Amino-benzyl)-methanesulfonamide (obtained in Step 2, 26.5 mmol) and 4.739 g 4,6-dichloropyrimidine (31.81 mmol) was dissolved in 120 cm3 of isopropyl-alcohol, 6.93 cm3 N,N-diisopropyl-ethylamine (5.140 g, 39.76 mmol) was added and the mixture was refluxed for four days. The reaction mixture was cooled to room temperature and the precipitated compound was filtered off. The light yellow product was washed well with diethyl-ether and air-dried. 3.612 g N-[3-(6-Chloro-pyrimidin-4-ylamino)-benzyl]-methanesulfonamide was obtained in more than 98% purity and in 44% overall yield. For analitical results and compound identification see Table 1. The compound was used as a starting material in the preparation of Example 2-32 and 75.
