The tube was sealed and the mixture was heated at 100° C. for 18 hours then cooled to room temperature, diluted with dichloromethane (30 mL) and washed with 2N Hydrochloric acid (10 mL). The organic layer was separated, dried over magnesium sulfate, filtered and evaporated. The residue was purified via chromatography (silica gel column 24 g and 10%→90% ethyl acetate:hexane). N-{2-[(E)-2-(2-Chloro-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-vinyl]-phenyl}-N-methyl-methanesulfonamide was isolated as a tan foam (0.133 g, 69%). 1H NMR (400 MHz, CDCl3, δ, ppm): 8.52 (d, J=16.1 Hz, 1H), 8.40 (d, J=6.8 Hz, 1H), 7.86 (d, J=7.1 Hz, 1H), 7.65 (d, J=7.4 Hz, 1H), 7.46-7.30 (m, 3H), 7.20-7.05 (m, 2H), 3.36 (s, 3H), 3.19 (s, 3H).
