Reaction Steps

A mixture of 3.67 g (12.2 mmoles) of 1-bromomethyl-7,8-dimethoxy-2-benzoxepin, 2.12 ml (12.2 mmoles) of diisopropylethylamine, and 15 ml of ethylene glycol is heated at 100° for 7 hours. The reaction mixture is then cooled and extracted with methylene chloride, then with water and finally with brine. The organic layer is filtered through Na2SO4, taken to dryness, and chromatographed on silica gel to give 3.06 g (89%) of 2-[(1,3,4,5-tetrahydro-7,8-dimethoxy-2-benzoxepin-1-yl)methoxy]ethanol: mass spectrum: M+ (m/e=282).
