Triethylamine → HCID 86626159, compound

Participants

Reaction Steps

Under a nitrogen atmosphere, a solution of tert-butyl {4-[3-amino-7-(benzyloxy)quinolin-4-ylamino]butyl}carbamate (28.62 g, 65.5 mmol) in dichloromethane (1 L) was cooled to ˜0° C.; triethylamine (10.0 mL, 72.1 mmol) was added. Methoxypropionyl chloride (8.57 mL, 78.6 mmol) was added dropwise, and the reaction was stirred at ambient temperature for two hours. The volatiles were removed under reduced pressure, and the residue was dissolved in ethanol (840 mL). Triethylamine (33 mL) was added, and the reaction was heated at reflux overnight and allowed to cool to ambient temperature. The volatiles were removed under reduced pressure to provide 30.77 g of tert-butyl {4-[7-benzyloxy-2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-1-yl]butyl}carbamate as a brown oil, which was used without purification.
