Reaction Steps

2-(2,6-Difluorophenyl)4-(4-bromophenyl)oxazoline (VP4) (5.00 g, 14.8 mmol) was mixed with 2-ethoxy-5-trimethylstannylpyridine (VP8) (5.06 g, 17.8 mmol), Pd(PPh3)4 (0.68 g, 0.59 mmol) and lithium chloride (0.12 g, 2.9 mmol) in dioxane (40 ml) and the mixture was refluxed under nitrogen (7 hours). After extraction and chromatography, 2-(2,6-difluorophenyl)4-[4-(2-ethoxypyridin-5-yl)phenyl]oxazoline was obtained, 3.86 g, m.p. 119° C.; 1H NMR (CDCl3, ppm): 1.42, 4.35, OCH2CH3; 4.40, 4.84, 5.51, oxazoline; 6.79, 7.77, 8.36, pyridine; 7.00, 7.41, 7.54, phenyl.
