Reaction Steps

A mixture of N-[(2Z)-2-amino-1-(cyclopropylmethyl)-2-hydroxyimino-1-methyl-ethyl]-5-cyclopropyl-4-(2,2,2-trifluoroethoxy)pyridine-2-carboxamide (example 165a, 30 mg, 74.9 μmol) in piperidine-1-carbonitrile (130 mg, 130 μl, 1.18 mmol) was heated at 130° C. in a sealed tube for 2 hours. The reaction mixture was cooled to room temperature and was diluted with ethyl acetate. The organic phase was washed with water. The organic phase was collected and the aqueous phase was back-extracted with ethyl acetate. Combined organic phases were dried over sodium sulfate and evaporated down to dryness. The crude material was purified by flash chromatography on silica eluting with a heptane/ethyl acetate gradient to yield the title compound (21 mg, 67%). MS (ESI, m/z): 426.6 (M+H+).
