実験手順
To a solution of tert-butyl 2-(3-methoxy-4-(methoxycarbonyl)phenyl)hydrazinecarboxylate (Intermediate 14, 1.5 g, 5.08 mmol) in DCM (20 mL) was added 2-chloro-5-(N-cyclopropylsulfamoyl)benzoyl isocyanate (1.6 g, 5.32 mmol). The reaction mass was stirred at RT for 2 h. Excess of solvent was removed under vacuum to afford 0.500 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 0.50 (m, 4H), 1.41 (s, 9H), 2.11 (m, 1H), 3.68-3.75 (m, 6H), 7.59 (d, J=8.7 Hz, 1H), 7.78-7.87 (m, 4H), 8.10 (m, 2H), 8.27 (s, 1H), 8.95 (s, 1H).
