Procedure
2-(1,3-Dioxo-1,3-dihydro-isoindol-2-ylmethyl)-oxazole-4-carboxylic acid [2-(3-chloro-phenyl)-ethyl]-amide (0.75 g, 1.8 mmol) was dissolved in ethanol (5 mL). Hydrazine monohydrate (0.44 mL, 9.2 mmol) was added. The mixture was stirred for 12 hours. A white precipitate formed during the course of the reaction. The mixture was filtered and the solid was washed with methanol. The filtrate was reduced in vacuo to afford the title compound: 1H NMR (400 MHz, d6-DMSO): 8.46 (s, 1H), 8.27 (t, 1H), 7.27 (m, 3H), 7.16 (m, 1H), 3.78 (s, 2H), 3.45 (m, 2H), 2.82 (t, 2H); MS (ESI-LCMS) for C13H14ClN3O2: 280 (MH+).
