Procedure

The title compound was prepared according to the procedure described in step-1 of Intermediate-9 by using 2,6-dichlorobenzoyl isocyanate (1.0 g, 3.38 mmol), tert-butyl 2-(3-methoxy-4-(methoxycarbonyl)phenyl)hydrazinecarboxylate (Intermediate-14, 0.805 g, 3.72 mmol) and DCM (20 mL) to afford 1.5 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 1.42 (s, 9H), 3.76 (s, 6H), 6.99 (d, J=6.0 Hz, 1H), 7.10 (s, 1H), 7.60-7.37 (m, 3H), 7.67 (d, J=7.8 Hz, 1H), 9.86 (br s, 1H), 11.30 (br s, 1H).
