Dimethylamine → HCID 17848809, compound

Participants

Reaction Steps

50% Aqueous dimethylamine (51 mL) was added to a solution of ethyl 6-(3-chloropropanoyl)-3,4-dihydro-1(2H)-quinoline carboxylate (15.0 g, 50.7 mmol) obtained in Reference Example 1 in dichloromethane at room temperature and then stirred for 2 hours. The reaction solution was separated, and the organic layer was washed with a saturated saline solution and dried over anhydrous sodium sulfate, and the solvent was distilled away under reduced pressure. The resultant residues were purified by alumina column chromatography (developing solvent; hexane:ethyl acetate=1:1), whereby the title compound (16.3 g) was obtained as pale yellow matter.
