Hydrochloric Acid → 1-(2-Iodophenyl)cyclopropanecarboxamide

Participants

Reaction Steps

HOBt (1.89 g, 14.0 mmol) and EDCl.HCl (2.69 g, 14.0 mmol) were added to a solution of 1-(2-iodophenyl)cyclopropanecarboxylic acid (I10) (3.11 g, 10.8 mmol) in DMF (6 mL), THF (29 mL) and Et3N (9.4 mL, 54 mmol). After 15 minutes ammonium carbonate (7.95 g, 86.4 mmol) was added and the resulting mixture was stirred at room temperature for 20 hours. The volatiles were removed in vacuo and water (150 mL) was added to the residue resulting in the formation of a suspension. The suspension was sonicated for several minutes, filtered and the filter cake dried to give the title compound I11 as an off white solid (2.55 g, 82%); 1H NMR (300 MHz, d6-DMSO) δ 7.87 (d, J=7.6 Hz, 1H), 7.36-7.38 (m, 2H), 7.02-7.08 (m, 1H), 6.96 (brs, 1H), 6.05 (brs, 1H), 1.52 (brs, 2H), 0.96 (brs, 2H). LCMS-B: rt 5.800 min; m/z 288 [M+H]+.
