Trifluoroacetic acid → HCID 15366668, compound

Participants

Reaction Steps

Trifluoroacetic acid (42 mL, 544 mmole) was added to a chilled (0° C.) solution of tert-butyl N-benzyloxy-N-(1-ethylpropyl)carbamate (21.6 g, 73.6 mmole) in methylene chloride (300 mL). The reaction was stirred at ambient temperature for about 18 hours then concentrated under vacuum. Saturated aqueous sodium bicarbonate (100 mL) was added to the residue followed by a quantity of solid sodium carbonate sufficient to adjust the pH of the reaction mixture to pH 9. The reaction mixture was extracted with diethyl ether (4×50 mL). The extracts were combined, dried over sodium sulfate then concentrated to provide 10.9 g of N-benzyloxy-N-(1-ethylpropyl)amine as an oil.
