Versuchsvorschrift

The mixture of methyl 4-[3-(2-chloro-6-fluorophenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]benzoate (step-2 of Intermediate-9, 0.100 g, 0.280 mmol), 1-[2-(trifluoromethyl)phenyl]methanamine (0.075 g, 0.430 mmol), 1,2,4-traizole (0.004 g, 0.05 mmol) and DBU (0.009 g, 0.005 mmol) was heated at 80-90° C. in seal tube for 15 h. The reaction mass was quenched in water and extracted with ethyl acetate. The organic layer was washed with dilute HCl and water, dried over anhydrous sodium sulphate and concentrated to afford 0.030 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 4.66-4.68 (d, J=4.2 Hz, 2H), 7.45-7.75 (m, 7H), 8.05 (s, 4H), 9.16 (br s, 1H), 12.73 (br s, 1H); MS (m/z): 489.42 (M−H)−.
