Following the procedure as describe in Example 6, making variations as required to replace 2-fluorobenzoyl chloride with 3-fluorobenzoyl chloride to react with 2-amino-N-benzylisonicotinamide, N-benzyl-2-(3-fluorobenzamido)isonicotinamide was obtained as a colorless solid in 44% yield: mp 140-143° C. (hexanes/ethyl acetate); 1H NMR (300 MHz, CDCl3) δ 8.71 (s, 1H), 8.60 (s, 1H), 8.41-8.39 (m, 1H), 7.70-7.55 (m, 3H), 7.51-7.44 (m, 1H), 7.37-7.25 (m, 6H), 6.76-6.66 (m, 1H), 4.65 (d, J=5.8 Hz, 2H); MS (ES+) m/z 350.5 (M+1).
