Versuchsvorschrift

The solution of 5-bromo-2-chloropyridine (1.5 g, 7.8 mmol), 1,4-oxazepane (1.29 g, 9.36 mmol) and K2CO3 in 15 mL of NMP was stirred at 120° C. overnight. The mixture was added to 150 mL of water, washed with EA, dried over Na2SO4, and the volatiles were removed in vacuo to give 1.86 g of 4-(5-bromopyridin-2-yl)-1,4-oxazepane. MS(m/z)=259 (M+H)+.
