Participants

Reaction Steps

2-[(1,3-Dioxo-2H-isoindol-2-yl)oxy]-2-propenoic acid (1.54 g, 4.8 mmole) was dissolved in 25 ml of acetonitrile and a solution of diphenyldiazomethane (1.17 g, 5.94 mmole/50 ml acetonitrile) was added dropwise. After approximately 1.1 equivalents of diphenyldiazomethane had been added, tlc showed no starting material remaining. The excess diphenyldiazomethane was decomposed with the addition of a small amount of acetic acid. The reaction solution was concentrated to a residue, dissolved in ethyl acetate, washed consecutively with 1N sodium bicarbonate and brine, dried over anhydrous magnesium sulfate and evaporated to a solid. After trituration with hexane, 1.9 g of the title compound was obtained.
