Reaction Steps
A mixture of N-(4-ethynylphenyl)isoindoline-2-carboxamide (100 mg, 0.381 mmol), benzylamine (33.2 mg, 0.381 mmol), and sodium ascorbate (15 mg, 0.076 mmol) in methanol (1.9 ml) was treated with 1H-imidazole-1-sulfonyl azide hydrochloride (66.0 mg, 0.381 mmol), copper(II) sulfate pentahydrate (9.52 mg, 0.038 mmol) and triethylamine (63.8 μl, 0.457 mmol). Additional methanol (2 mL) was added and the vial was flushed with nitrogen and stirred for 2 days. The mixture was diluted with water and the resulting suspension was filtered with water washes to provide the title compound as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 8.51 (s, 1H), 8.45 (s, 1H), 7.73 (d, J=8.7 Hz, 2H), 7.65 (d, J=8.9 Hz, 2H), 7.49-7.24 (m, 9H), 5.63 (s, 2H), 4.78 (s, 4H), 1.11-1.00 (m, 1H); MS (ESI(+)) m/e 396 (M+H)+.
