Reaction Conditions

Reaction Steps

N-(1-Acetyl-5-chloromethyl-4,6-dimethylindolin-7-yl)-2,2-dimethylpropanamide (7.0 g) was dissolved in a mixed solvent (50 ml) of CH3CN/DMF=1/1. Potassium acetate (12.0 g) was added and the mixture was stirred at 60° C. for 1 hr. CH3CN was evaporated under reduced pressure and AcOEt (200 ml) was added. After washing with water, the mixture was dried over anhydrous sodium sulfate, and AcOEt was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: CHCl3 /MeOH=1/0-10/1) to give 7.5 g of N-(1-acetyl-5-acetoxymethyl-4,6-dimethylindolin-7-yl)-2,2-dimethylpropanamide.
