Hydrochloric Acid → 4-Chloro-N-(2-hydroxyethyl)benzamide

Participants

Reaction Steps

2.6 ml (0.02 mol) of 4-chlorobenzoyl chloride are added dropwise at 0° to a solution of 1.2 ml (0.02 mol) of ethanolamine and 3 ml (about 0.02 mol) of triethylamine in 30 ml of methylene chloride. The mixture is then poured into dilute hydrochloric acid and extracted twice with methylene chloride. The methylene chloride extracts are dried over magnesium sulfate and concentrated. After purification on silica gel using chloroform and chloroform/methanol 9:1) as the eluting agent, there are obtained 3.1 g of N-(2-hydroxyethyl)-4-chlorobenzamide.
