Triethylamine → 2-(6,11-Dihydrodibenz[b,e]oxepin-2-yl)ethanol methanesulfonate

Participants

Reaction Steps

2-(6,11-Dihydrodibenz[b,e]oxepin-2-yl)ethanol (14 g) and triethylamine (6.7 g) in 200 ml of dry dichloromethane was treated with methanesulfonylchloride (5.2 ml) and stirred at room temperature for 2 hours. This solution was evaporated to a paste, taken up in ethyl acetate, washed dried, and evaporated to an oil. Passage through a short pad of silica gel with chloroform as eluent gave 13.5 g of 2-(6,11-dihydrodibenz[b,e]-oxepin-2-yl)ethanol methanesulfonate as an oil.
