Ethylene Glycol → 6-(4-Nitrophenoxy)hexanoic acid 2-hydroxyethyl ester

Participants

Reaction Steps

Dry HCl gas was passed through a mixture of 6-(4-nitrophenoxy)-hexanoic acid 35 (50 g, 197.62 mmol) and ethylene glycol (200 ml) was passed dry HCl gas for one hour. During HCl gas bubbling the temperature rose to 60° C. The crude reaction mass was poured onto ice (1 kg), extracted in to ethyl acetate, washed with water (2×250 ml), dried over sodium sulphate and distilled to get crude 36, which was purified by column chromatography on silica gel using benzene as eluant to get pure 36 (46 g, 78.3) as a light yellow syrup.
