Procedure

The title compound was prepared according to the procedure described in Example-83 by using tert-butyl 2-(4-(trifluoromethyl)phenyl)hydrazinecarboxylate (Intermediate-53, 1.00 g, 3.63 mmol), 3-((2,2,2-trifluoroacetamido)methyl)-2,6-dimethylbenzoyl isocyanate (Intermediate-65, 1.00 g, 3.33 mmol), DCM (20 mL), trifluoro acetic acid (5.0 mL) to afford 0.700 g of the desired product. 1H NMR (400 MHz, DMSO d6): δ 2.20 (s, 3H), 2.22 (s, 3H), 4.40 (d, J=4.2 Hz, 2H), 7.21 (d, J=6.0 Hz, 1H), 7.29 (d, J=6.0 Hz, 1H), 7.82 (d, J=6.6 Hz, 1H), 8.17 (d, J=6.6 Hz, 1H), 9.95 (t, J=6.9 Hz, 1H), 12.32 (br s, 1H); MS (m/z): 457.26 (M−H)−.
