Reaction Steps

2-(2,6-Difluorophenyl)-4-(4-bromophenyl)oxazoline (VP4) (2.0 g, 2.9 mmol) was mixed with 2-n-propyloxy-5-trimethylstannylpyridine (4.6 g, 50%, 7.7 mmol), Pd(PPh3)4 (0.35 g, 0.3 mmol) and lithium chloride (50 mg) in dioxane and refluxed under nitrogen (7 hours). After chromatography and recrystallization in heptane/ethyl acetate 95:5, 2-(2,6-difluorophenyl)-4-[4-(2-n-propyloxypyridin-5-yl)phenyl]oxazoline was obtained, 1.21 g, colorless crystals;
