Reaction Steps

The title compound was prepared according to the procedure described in Example-83 by using 3-fluoro-4-iodobenzoyl isocyanate (Intermediate-102, 1.0 g), tert-butyl 2-(2-chloro-5-{[(2-methylpropanoyl)amino]methyl}phenyl)hydrazinecarboxylate (Intermediate-97, 0.800 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 1.30 (s, 6H), 2.43-2.45 (m, 1H), 4.26 (m, 2H), 7.01 (m, 1H), 7.46-7.49 (m, 1H), 7.63-7.66 (m, 1H), 7.84-7.91 (m, 1H), 8.01-8.06 (m, 1H), 8.22 (s, 1H), 8.36 (br s, 1H), 12.66 (m, 1H); MS (m/z): 515.21 (M+H)+.
