Trimethylaluminum → 4-(3-(2-chloro-5-((2,2,2-trifluoroacetamido)methyl)phenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)-N-(3-(difluoromethyl)phenyl)-2-methoxybenzamide

Participants

Reaction Steps

The title compound was prepared according to the procedure described in step-6 of Intermediate-26 by using methyl 4-(3-(2-chloro-5-((2,2,2-trifluoroacetamido)methyl)phenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl)-2-methoxybenzoate (step-5 of Intermediate-26, 0.100 g, 0.20 mmol), 3-(difluoromethyl)aniline (Intermediate-29, 0.045 g, 0.30 mmol), trimethyl aluminium (2M solution in toluene) (1.0 mL) and dry toluene (5.0 mL) to afford 0.080 g of crude product which was triturated with methanol:DCM:ether to afford 0.080 g of pure product. 1H NMR (300 MHz, DMSO do): δ 3.95 (s, 3H), 4.47 (d, J=5.7 Hz, 2H), 7.05 (m, 1H), 7.30 (m, 1H), 7.50 (d, J=7.8 Hz, 2H), 7.70 (m, 3H), 7.80 (d, J=6.3 Hz, 3H), 8.08 (s, 1H), 10.11 (br s, 1H), 10.28 (s, 1H), 12.72 (br s, 1H); MS (m/z): 596.12 (M+H)+.
