Procedure

The title compound was prepared according to the procedure described in Example-83 by using 4-chloro-3-(trifluoromethyl)benzo yl isocyanate (Intermediate-100, 2.0 g), tert-butyl 2-(2-chloro-5-{[(2,2-dimethylpropanoyl)amino]methyl}phenyl)hydrazinecarboxylate (Intermediate-94, 1.0 g), DCM (15 mL), and trifluoro acetic acid (3.0 mL) to afford 0.900 g of the desired product. 1H NMR (300 MHz, DMSO d6): δ 1.12 (s, 9H), 4.29 (d, J=5.1 Hz, 2H), 7.36 (d, J=9.3 Hz, 1H), 7.43 (s, 1H), 7.61 (d, J=8.4 Hz, 1H), 7.93 (d, J=9.0 Hz, 1H), 8.10-8.18 (m, 2H), 8.27 (s, 1H), 12.82 (s, 1H); MS (m/z): 487.29 (M+H)+.
