Reaction Steps

A mixture of N-{5-[(cyclopropylamino)carbonyl]-2-methylphenyl}-3,4,5-trifluorobenzamide (100 mg, 0.29 mmol), 2-pyridinylmethanol (400 μl) and potassium t-butoxide (32 mg, 0.29 mmol) in NMP (600 μl) was heated in the microwave at 180° C. for 1.5 hrs. The reaction mixture was cooled and partitioned between saturated aqueous sodium bicarbonate and ethyl acetate. The organic phase was washed with dilute aqueous citric acid. Evaporation of the ethyl acetate gave impure product which was purified on silica column chromatography eluting with 0 to 100% ethyl acetate in isohexane. The solvents were evaporated to give a residue which was dissolved in ethyl acetate, then extracted with dilute hydrochloric acid. The aqueous extracts were basified with saturated aqueous sodium bicarbonate solution and then extracted with ethyl acetate to give the title compound as a solid (29 mg, 23%); NMR Spectrum: (DMSOd6) 0.58 (m, 2H), 0.69 (m, 2H), 2.25 (s, 3H), 2.85 (m, 1H), 5.36 (s, 2H), 7.37 (m, 2H), 7.64 (m, 2H), 7.84 (m, 4H), 8.40 (m, 1H), 8.56 (m, 1H), 10.14 (s, 1H); Mass Spectrum: M−H− 436.
