Reaction Steps

The title compound was prepared by following the procedure as described for Example-83 by using tert-butyl 2-(cyclohexyl)hydrazinecarboxylate (Intermediate-64, 0.050 g, 0.23 mmol), 6-chloro-2-fluoro-3-(pivalamidomethyl)benzoyl isocyanate (Intermediate-51, 0.225 g, 0.70 mmol), DCM (10 mL) and TFA (3 mL) to afford 0.015 g of pure product. NMR (400 MHz, DMSO d6): δ 1.13 (s, 9H), 1.22-1.23 (m, 2H), 1.30-1.37 (m, 2H), 1.62-1.64 (m, 2H), 1.78-1.81 (m, 4H), 3.90-3.92 (m, 1H), 4.27-4.28 (d, J=4.8 Hz, 2H), 7.37-7.41 (t, 1H), 7.46-7.48 (d, 1H), 8.17 (br s, 1H); MS (m/z): 409.36 (M+H+).
