Triethylamine → HCID 66765094, compound

Participants

Reaction Steps

A solution of valeryl chloride (13.3 mL, 112 mmol) in dichloromethane (35 mL) was added dropwise to a stirred solution of 3-amino-4-chloroquinoline (10.0 g, 56 mmol) and triethylamine (2.1 mL, 15 mmol) in dichloromethane (100 mL), and the reaction was stirred overnight at room temperature and then stirred for one hour with saturated aqueous sodium bicarbonate (150 mL). The aqueous layer was separated and extracted with dichloromethane (2×50 mL). The combined organic fractions were washed with saturated aqueous sodium bicarbonate (50 mL), dried over potassium carbonate, filtered, and concentrated under reduced pressure. The residue was recrystallized from toluene/hexane to provide 11.1 g of N-(4-chloroquinolin-3-yl)pentanamide as a light brown solid.
