Ammonium Hydroxide → 4-tert-Butylbenzene-1,2-dicarboxamide

Participants

Reaction Steps

A 4 liter conical flask was then charged with 137.4 grams (0.6757 mole) of 4-t-butylphthalimide and 2 liters of 29 percent ammonium hydroxide solution and the solution was stirred vigorously with a mechanical stirrer. After 3 hours, the creamy suspension was suction filtered and washed with a small amount of water. The faint green powder was dried at 120° C. for one day to yield 134.19 grams of 4-t-butylphthalamide, which exhibited a melting point of 172° to 175° C. The identity of the 4-t-butyl-phthalamide product was confirmed by IR spectrum.
