Reaction Steps

To 4.4 g of (1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)acetyl chloride in 20 ml of pyridine are added 1.48 g of acetamidoxime, and the mixture is refluxed for 1 hour. The reaction medium is concentrated and taken up in ethyl acetate and water. The organic phase is dried over anhydrous sodium sulfate and concentrated. The residue is chromatographed on a column of silica gel, eluting with a 7/3 (v/v) toluene/ethyl acetate mixture to give 1.2 g of expected product.
