2-(Dimethylamino)ethanol → HCID 53923166, compound

Participants

Reaction Steps

The acid chloride, prepared from 4-[[2-(2-naphthalenyloxy)ethyl]oxy]-alphaoxobenzeneacetic acid (0.5 g) as described in Example 6, was dissolved in dichloromethane (10 mL) and added dropwise to a stirred, cold (<-50° C.) mixture of 2-(dimethylamino)ethanol (0.178 g) in dichloromethane (10 mL). The cooling bath was removed and the mixture stirred for 1 hour at room temperature. The mixture was diluted with dichloromethane and washed once with saturated aqueous sodium bicarbonate, once with water, and the organic solution was dried (Na2SO4), filtered, and evaporated to give crude product. Crystallization from diethyl ether-hexane provided pure 4-[[2-(2-naphthalenyloxy)ethyl]oxy]-alpha-oxobenzeneacetic acid 2-(dimethylamino)ethyl ester as a colorless solid, mp 93°-94° C.
