Reaction Steps

N-(5-Dimethylaminomethyl-4,6-dimethylindolin-7-yl)-2,2-dimethyl-propanamide (700 mg) was dissolved in DMF (7 ml) and NaH (P=60%, 160 mg) was added under a nitrogen atmosphere at 5° C. After stirring at the same temperature for 30 min, 1-iodooctane (240 mg) was added, which was followed by stirring at 30° C. for 3 hr. AcOEt (200 ml) was added, and the mixture was washed with water and dried over anhydrous sodium sulfate. AcOEt was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: CHCl3/MeOH=10/1−3/1) to give 500 mg of the title compound.
