Procedure

The title compound was prepared by following the procedure as described for Example-31 by using methyl 4-(3-(2-chloro-5-(cyclopropane carboxamidomethyl)phenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)benzoate (Intermediate-42, 0.100 g, 0.24 mmol), 3-(trifluoromethyl)aniline (0.050 g, 0.36 mmol), trimethyl aluminium (2M solution in toluene) (1 mL) and dry toluene (8.0 mL). The reaction mass was quenched in water, extracted with DCM and the organic layer was concentrated to afford 0.010 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 0.70 (s, 4H), 1.62 (m, 1H), 4.33 (d, J=6.3 Hz, 2H), 7.44-7.67 (m, 4H), 8.10-8.26 (m, 6H), 8.68 (m, 1H), 10.53 (s, 1H), 12.68 (br s, 1H); MS (m/z): 554.30 (M−H)−.
