Participants

Reaction Conditions

Reaction Steps

Slowly add sodium hydride (60% dispersion in mineral oil, 1.75 g, 43.7 mmol) to a 0° C. solution of N-[tert-butoxycarbonyl]N-allyl N-[(1H-indol-7-yl)methyl]amine (6.6 g, 23 mmol) in anhydrous dimethylformamide. Warm the mixture to 20-24° C., stir for 30 minutes, add allyl bromide (4.0 mL, 46 mmol), and stir the mixture at 20-24° C. overnight. Dilute the reaction mixture with ethyl acetate (450 mL), wash sequentially with water (2×100 mL) and saturated aqueous sodium chloride (150 mL), dry over sodium sulfate, filter, and concentrate under reduced pressure. Subject the residue to silica gel chromatography, eluting with 10% ethyl acetate in hexanes. Combine fractions containing product and concentrate them under reduced pressure to provide the desired compound as a light brown oil (6.8 g, 91%).
