Pyridine → Ethyl 2-(2-acetamido-3-phenoxyphenyl)acetate

Participants

Reaction Steps

A solution of acetyl chloride (1.38 g.) in methylene chloride (10 ml.) was added to a mixture of ethyl 2-(2-amino-3-phenoxyphenyl)acetate (4.3 g.), pyridine (1.9 g.) and dried methylene chloride (50 ml.) over 10 minutes at 5° C. with stirring and stirred for 30 minutes at the same temperature. The reaction mixture was concentrated under reduced pressure and to the residue was added 10% hydrochloric acid. The mixture was extracted with ethyl acetate, and the extract was washed with water, dried over magnesium sulfate and then evaporated. The residue was crystallized with a mixture of benzene and n-hexane to give the captioned compound (3.65 g.). mp 106° to 107° C.
