Reaction Steps

1-oxoisoindoline-5-carbonitrile. To methyl 2-(bromomethyl)-4-cyanobenzoate (0.3 g, 1.18 mmol) in a sealed tube, was added 7N NH3 in MeOH (10 mL). The tube was then sealed and the reaction stirred at 40° C. for 18 h. The reaction progress was monitored by TLC (90% EtOAc in hexanes). The reaction was filtered to give the title compound as a white solid. 1H NMR (400MHz, DMSO-d6): δ 8.95 (s, 1H), 8.1 (s, 1H), 7.9 (d, J=8.0 Hz, 1H), 7.8 (d, J=8.0 Hz, 1H), 4.4 (s, 2H).
