Dimethylamine → HCID 17848835, compound

Participants

Reaction Steps

50% aqueous dimethylamine (27 ml) was added to a solution of 1-(1-acetyl-2,3,4,5-tetrahydro-1H-1-benzazepin-8-yl)-3-chloro-1-propanone (7.10 g, 25.4 mmol) obtained in Reference Example 7 in dichloromethane at room temperature, and then stirred for 4 hours. After the reaction solution was separated, 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) and crystallized from hexane, whereby the title compound (5.38 g) was obtained as colorless powder with a mp. of 68 to 70° C.
