Ethylene Glycol → (4-Nitrophenoxy)-acetic acid-2-hydroxy-ethyl ester

Participants

Reaction Steps

To a mixture of (4-nitrophenoxy)acetic acid 40 (100 g, 507 mmol) and ethylene glycol (300 ml) was passed dry HCl gas for 1 hr. During HCl gas bubbling the temperature rose to 60° C. The crude reaction mass was poured onto ice (2 Kg). Crude 41 was filtered, dried and purified by column chromatography on silica gel using hexane:ethyl acetate (95:5) to give pure 41 (70 g, 57.4%) as a white powder. M.p: 73.5-75.5° C.
