Participants

Reaction Steps

To a solution of tert-butyl (1-oxo-2,3-dihydro-1H-inden-5-yl)carbamate (371 mg, 1.5 mmol) in dimethylamine (2.0 M solution in THF, 5 mL, 10 mmol) was added sodium triacetoxyborohydride (636 mg, 3.0 mmol). The resultant suspension was stirred at room temperature for 16 h, diluted with a saturated NaHCO3 solution and extracted with ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated. Purification by column chromatography (silica, 0-20% methanol/dichloromethane) afforded the desired product (225 mg, 54%) as an off-white solid. ESI MS m/z 277 [C16H24N2O2+H]+
