실험 절차

29.1 gm of 4,4-dimethyl-7-acetamino-8-nitro-2H,4H-isoquinoline-1,3-dione were refluxed for 4 hours with 50 ml of propionic acid anhydride. The mixture was then poured into ice water and neutralized with sodium bicarbonate. The obtained precipitate was purified on a silicagel column (eluant: chloroform/acetone 19:1).
