Reaction Steps

2-(3-Methoxy-azetidin-1-yl)-5-nitro-pyridine (120 mg, 0.5 mmol) was hydrogenated as above and reacted with 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid (141 mg, 0.55 mmol), Et3N (352 uL, 2.5 mmol) and BOP (232 mg. 0.525 mmol). Following work-up as above, the crude material was purified by flash chromatography to yield 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid [6-(3-methoxy-azetidin-1-yl)-pyridin-3-yl]-amide as a light green solid (45 mg). ES-MS calcd for C20H17F3N4O3 (m/e) 418.38, obsd 419.1 (M+H).
