Reaction Steps

To a solution of homophthalic anhydride (324 mg, 2.0 mmol) in acetonitrile (15 mL) was added 2-cyanobenzyl bromide (431 mg, 2.0 mmol, 1.0 eq) and triethylamine (5 mL). The reaction was stirred under inert atmosphere at room temperature for 30 minutes, after which time a yellow precipitate appeared. The reaction mixture was then heated at reflux for 18 h and the resulting white precipitate was filtered, washed using acetonitrile (3×8 mL) and dried under vacuum to provide Compound 13a as a white crystalline solid. Yield=150 mg (32%).
