Reaction Steps

2-t-Butylindoline (20.3 g, 116 mmol) (can be made according to the procedures described in J. Chem Soc. Chem. Commum. 1974, 677-678) and 4-dimethylaminopyridine (10 mg) are dissolved in pyridine (100 ml). Acetic anhydride (11.5 ml, 122 mmol) is added and the solution stirred for 2 hours. The mixture is poured into water (1 L) and the solid filtered and dried in vacuo. The title compound is obtained as white crystals (22.2 g, 88%): mp 75° C.
