Participants

Reaction Steps

To a solution of indoline (2.0 mL, 17.8 mmol) in MeCN (45.0 mL) was added 3,4-dichlorobenzoyl chloride (4.11 g, 19.6 mmol) followed by Et3N (7.5 mL, 53.5 mmol) at 0° C. The reaction mixture was stirred at room temperature for 1 h and then concentrated in vacuo. The residue was triturated with water and dried under high vacuum to give the title compound (5.2 g, 100%) as a light brown solid. 1H NMR (DMSO-d6) δ 7.89 (d, J=1.1 Hz, 1H), 7.77 (d, J=8.1 Hz, 1H), 7.60 (d, J=8.1 Hz, 1H), 7.29 (d, J=7.3 Hz, 1H), 7.19 (m, 1H), 7.06 (t, J=7.2 Hz, 1H), 4.00 (t, J=8.3 Hz, 2H), 3.09 (t, J=8.3 Hz, 2H); MS(ESI+) m/z 292.1 (M+H)+.
