実験手順
To a solution of 2-chloro-5-(chlorosulfonyl)benzoic acid (4.0 g, 15.68 mmol) in DCM (60 mL) was added cyclopropyl amine (1.8 g, 31.57 mmol) and the reaction mixture was stirred at RT for 16 h. The reaction mass was concentrated and the residue was diluted with ice cold water and acidified with dilute HCl. The crude solid was filtered off, washed with water and dried to afford 3.0 g of pure product. 1H NMR (300 MHz, DMSO d6): δ 0.37 (s, 2H), 0.49 (d, J=5.4 Hz, 2H), 2.12-2.13 (m, 1H), 7.82 (d, J=8.4 Hz, 1H), 7.91 (d, J=8.4 Hz, 1H), 8.13 (s, 1H), 8.18 (s, 1H), 13.92 (br s, 1H).
