Methyl-(3-methyl-butyl)-(5-nitro-pyridin-2-yl)-amine (110 mg, 0.49 mmol) was hydrogenated as above and reacted with 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid (138 mg, 0.54 mmol), Et3N (352 uL, 2.5 mmol) and BOP (227 mg. 0.514 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-[methyl-(3-methyl-butyl)-amino]-pyridin-3-yl}-amide as a light purple solid (16 mg). ES-MS calcd for C22H23F3N4O2 (m/e) 432.51, obsd 433.2 M+H).
