Versuchsvorschrift

Methanesulphonyl chloride (0.74 g) in dichloromethane (5 ml) was added over 2 min to a stirred solution of 2-amino-6-bromopyridine (1.1 g) and pyridine (0.57 g) in dichloromethane (5 ml). After 4 h, the solvent was evaporated in vacuo to give an oil which was purified by FCC eluting with System A (95:5:1) to give the title compound as a white solid (1.2 g), m.p. 90°-94° C.
