反応手順

To a solution of 6.8 g of 5-{5-[2,6-dichloro-4-(4,5-dihydro-2-oxazolyl)phenoxy]pentyl}-3-isoxazolemethanol (Example 116) in 100 ml of dry tetrahydrofuran was added 0.45 g of sodium hydride. After hydrogen evolution had ceased, the solution was cooled in an ice-bath and 1.1 ml of methyl iodide was added. The reaction mixture was stirred at room temperature for 48 hrs, then diluted with ether and washed well with water. Evaporation of the solvent and chromatography provided 3.1 g of the product as a viscous yellow oil.
