Participants

Reaction Steps

A mixture of 4-(2,4-dichlorophenyl)-2-(2-fluoropyridin-4-yl)-5-(4H-1,2,4-triazol-3-yl)thiophene-3-carbonitrile (0.600 g, 0.00144 mol) and 7 M ammonia in methanol (40 mL, 0.280 mol) was irradiated in a microwave at 150° C. for 8 hours. Solvent was evaporated and the residue was purified by column chromatography on silica gel (40 g), gradient DCM to 6% MeOH in DCM over 30 minutes to afford the title compound as yellow solid (0.26 g, 44%). LCMS: (FA) ES+, 413, 415. 1H NMR (400 MHz, d4-Methanol) 8.40 (s, 1H), 8.05 (dd, J=5.16, 1.10 Hz, 1H), 7.61 (dd, J=1.54, 0.76 Hz, 1H), 7.46-7.42 (m, 2H), 7.03-7.00 (m, 2H)
