Reaction Steps

17.9 gm (0.1 mol) of p-aminophenethyl acetate were dissolved in 180 ml of acetonitrile, 27.6 gm (0.2 mol) of potassium carbonate were added to the solution, and then, while stirring, 17.0 gm (0.12 mol) of 4-chlorobutyric acid chloride were added dropwise. The resulting mixture was stirred for 2 hours at room temperature, thereafter heated to 50°C and then vacuum-filtered to remove precipitated inorganic salts. The solvent was distilled out of the filtrate in vacuo, and the residue was recrystallized from isopropanol, yielding 14.8 gm (52.2% of theory) of p-(4-chlorobutyramido)-phenethyl acetate, m.p. 83°C.
