Tert-Butyl hypochlorite → 2-Chloro-4-sec-butoxyphenol

Participants

Reaction Steps

To a solution of 5.0 g of 4-sec-butoxyphenol in 50 ml of carbon tetrachloride, there was added dropwise 3.27 g of t-butylhypochlorite with vigorously stirring and ice-cooling. After completion of the addition, the reaction mixture was stirred at room temperature for 5 hours and concentrated, followed by addition of 200 ml of ethyl acetate. The obtained solution was washed with an agueous solution of 5% wt. sodium dicarbonate, dried and concentrated under reduced pressure. The residue was subjected to silica gel chromatography to give 5.32 g of 4-sec-butoxy-2-chlorophenol. Yield. 88%. nD23.5 1.5312.
