The title compound was prepared according to the procedure described in step-2 of Intermediate-9 by using tert-butyl 2-((2,6-dichlorobenzoyl)carbamoyl)-2-(3-methoxy-4-(methoxycarbonyl)phenyl)hydrazinecarboxylate (1.5 g, 2.2 mmol), DCM (50 mL) and trifluoro acetic acid (5.0 mL) to afford 0.900 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 3.78 (s, 3H), 3.84 (s, 3H), 7.62-7.30 (m, 5H), 7.82 (d, J=8.7 Hz, 11), 12.76 (br s, 1H); MS (m/z): 393.85 (M+H)+.
