Procedure
To a solution of 1 eq. (0.1 g, 0.473 mmol) of 3-(pyridin-3-yloxy)-5-cyano-aniline in 0.47 M in CH2Cl2 (1 mL) and 1.6 eq. of pyridine (0.56 g, 0.71 mmol) was added 3 eq. of 4-fluorobenzoyl chloride (0.225 g, 1.42 mmol) and the resultant mixture stirred at rt overnight. The reaction mixture was diluted with CH2Cl2, washed with sat. NaHCO3, dried (Na2SO4) and concentrated in vacuo. The resultant residue was diluted with toluene and concentrated in vacuo (5 times). Purification by chromatography over silica with 5% MeOH/CH2Cl2 as the eluant afforded 134 mg of a the desired title compound of Formula I, N-[3-cyano-5-(pyridin-3-yloxy)-phenyl]]-4-fluoro-benzamide, as a solid (85% yield). Mpt 169-172° C. MS (M−1) 332.3.
