Reaction Steps

A solution of ethyl 3-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-2-oxopropanoate [J. Org. Chem.,(1985), 50 (1), 91](4.29 g, 16.4 mmol), acetamidrazone hydrochloride (1.80 g, 16.4 mmol) in anhydrous EtOH (85.8 mL) was heated to 80° C. for 3 h then cooled to rt and stirred for an additional 16 h. The reaction mixture was filtered through a fritted funnel resulting in 3.28 g, (73% yield) of the title compound as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 2.28 (s, 3H), 4.73 (s, 2H) and 7.74-8.12 (m, 4H); MS (ES+): m/z 271.08 [MH+].
