Procedure

The title compound was prepared by following the procedure as described for Example-83 by using tert-butyl 2-(6-chloro-2-fluoro-3-(pivalamidomethyl)phenyl)hydrazinecarboxylate (Intermediate-57, 0.050 g, 0.13 mmol), 4-(trifluoromethyl)benzoyl isocyanate (Intermediate-59, 0.060 g, 0.26 mmol), DCM (10 mL) and TFA (3 mL) to afford 0.045 g of desired product. 1H NMR (400 MHz, DMSO d6): δ 1.12 (s, 9H), 4.30 (d, J=4.4 Hz, 2H), 7.41 (t, J=8 Hz, 1H), 7.53 (d, J=8.5 Hz, 1H), 7.91 (d, J=8.4 Hz, 2H), 8.0 (d, J=8.2 Hz, 2H), 8.17 (t, J=5.8 Hz, 1H), 12.9 (br s, 1H); MS (m/z): 471.10 (M+H+).
