실험 절차

To a solution of tert-butyl 2-(2-chloro-5-(cyclopropanecarboxamidomethyl)phenyl)-2-((2-fluoro-4-iodobenzoyl)carbamoyl)hydrazinecarboxylate (0.200 g, 0.31 mmol) in DCM (10 mL) was added trifluoro acetic acid (1.0 mL). The reaction mass was stirred at RT for 12 h and refluxed for 15 h. The reaction mass was cooled to RT, basified with NaHCO3 (pH=8), extracted with DCM and concentrated to afford 0.110 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 0.68 (m, 4H), 1.59 (m, 1H), 4.32 (d, J=5.7 Hz, 2H), 7.38 (d, J=8.4 Hz, 1H), 7.45 (s, 1H), 7.51-7.63 (m, 2H), 7.75 (d, J=8.1 Hz, 1H), 7.88 (d, J=10.2 Hz, 1H), 8.68 (m, 1H), 12.43 (br s, 1H); MS (m/z): 513.01 (M+H)+.
