実験手順: To sodium hydride (0.53 g, 50% in oil, 11.0 mmol) in 40 ml of DMF, under N2 at 5°, is added, dropwise and with vigorous stirring, a solution of 4-(1-methylpropoxy)phenol (1.66 g, 10.0 mmol) in 10 ml of DMF. After the mixture is stirred at RT for 1 hour, a solution of 2-mesyloxymethyl-1,4-benzodioxin (2.70 g, 11.0 mmol) in 10 ml of DMF is slowly added. The resulting reaction mixture is stirred at RT for 48 hours and is then mixed with water and extracted with ether. The combined organic extracts are washed with water and with brine, dried and solvent removed and the product is purified by column chromatography to give 2-[4-(1-methylpropoxy)phenoxymethyl]-1,4-benzodioxin, MS m/e 315 (M+). The resulting reaction mixture is stirred at RT for 48 hours extracted with ether The combined organic extracts are washed with water and with brine dried solvent removed the product is purified by column chromatography

実験手順: 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. ice-cooling After completion of the addition the reaction mixture was stirred at room temperature for 5 hours 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 concentrated under reduced pressure
