反応手順

In 30 ml of methylene chloride were dissolved 2.1 g of 2-[3-[1-(1H-tetrazol-5-yl)ethoxy]phenoxy]aniline and 2.2 g of triethylamine, followed by dropwise addition of a solution of 1.7 g of 4-hexyloxybenzoyl chloride in benzene with ice-cooling and stirring. The mixture was stirred at room temperature overnight and refluxed for 1 hour. To the reaction mixture was added ice-water and after the mixture was acidified with diluted hydrochloric acid, the methylene chloride layer was separated. The methylene chloride solution was dried over magnesium sulfate and concentrated and the oily residue was subjected to silica gel column chromatography using chloroform-methanol (100:1) as the eluent to give 2.2 g of the title compound as a light yellow oil.
