Dimethylamine, hydrochloride → HCID 66846346, compound

Participants

Reaction Steps

A solution is prepared of 1.2 g (4.06 mmol) of 4-[2-(Boc-amino)ethoxy]benzeneacetic acid in 4 ml of dichloromethane and then 932 mg (4.87 mmol) of EDCI and 55 mg (0.406 mmol) of HOAT are added. After 10 minutes under agitation at ambient temperature, 400 mg (4.87 mmol) of dimethylamine hydrochloride are added. The reaction medium is then agitated at ambient temperature for 24 hours. The medium is then treated by the addition of 20 ml of water and then extracted 3 times with 50 ml of dichloromethane. The organic phases are then regrouped and washed 3 times with 50 ml of water, then dried on magnesium sulfate, and concentrated under reduced pressure. The raw product obtained is then purified by silica gel chromatography eluting with the help of a dichloromethane/ethanol mixture (95/5; v/v). In this way the expected product is obtained in the form of a colorless oil (yield=46%).
