Participants

Reaction Steps

A solution of 5-cyano-N-(4-(propylcarbamoyl)phenyl)isoindoline-2-carboxamide (30 mg, 0.9 mmol) in sulfuric acid (0.1 mL) and trifluoroacetic acid (0.3 mL) was stirred at room temperature for 16 hours. The reaction was treated with ice and the suspension was stirred for 10 minutes and filtered. The solid collected was washed with water and dried under vacuum; the solid was purified by reverse-phase HPLC to provide the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 8.61 (s, 1H), 8.26 (t, J=5.7 Hz, 1H), 7.97-8.00 (bs, 1H), 7.81-7.86 (m, 2H), 7.75-7.79 (m, 2H), 7.63-7.68 (m, 2H), 7.44 (d, J=7.8 Hz, 1H), 7.34-7.39 (bs, 1H), 4.81-4.82 (bs, 4H), 3.16-3.24 (m, 2H), 1.46-1.59 (m, 2H), 0.89 (t, J=7.4 Hz, 3H); MS (ESI(+)) m/e 367 (M+H)+.
