Procedure

The title compound was prepared by following the procedure as described for Example-83 by using tert-butyl 2-(4-methoxyphenyl)hydrazinecarboxylate (Intermediate-55, 0.060 g, 0.21 mmol), 6-chloro-2-fluoro-3-(pivalamidomethyl)benzoyl isocyanate (Intermediate-51, 0.101 g, 0.32 mmol), DCM (10 mL) and TFA (3 mL) to afford 0.018 g of pure product. 1H NMR (400 MHz, CDCl3): δ 1.20 (s, 9H), 3.82 (s, 3H), 4.46 (d, J=5.8 Hz, 2H), 6.12 (m, 1H), 6.95 (d, J=8.9 Hz, 2H), 7.26-7.30 (m, 1H), 7.43 (t, J=7.9 Hz, 1H), 7.82 (d, J=8.9 Hz, 2H), 11.01 (br s, 1H); MS (m/z): 433.20 (M+H+).
