实验步骤: The title compound was prepared by the procedure of Example 33 from sulfamoyl chloride and 2-(2-methoxyphenoxy)ethanol. The solid obtained was dissolved in 150 ml of methylene chloride, and the solution was treated with charcoal and filtered through Celite®. The filtrate was evaporated under reduced pressure and the solid residue was recrystallized from methylene chloride-petroleum ether (bp range 30°-60° C.) to give the title compound in 25% yield as white solid, mp 102°-104° C. The solid obtained filtered through Celite® The filtrate was evaporated under reduced pressure the solid residue was recrystallized from methylene chloride-petroleum ether (bp range 30°-60° C.)

实验步骤: A solution of 43.2 g (0.35 mole) of 2-methoxyphenol (guaiacol, Aldrich) in 200 ml of ethanol was stirred and treated with 29 ml (0.36 mole) of 50% sodium hydroxide solution. To this solution was added a solution of 28.2 g (0.35 mole) of 2-chloroethanol (Aldrich) in 50 ml of ethanol and the reaction mixture was heated at reflux for 2 hr. The solids were removed by filtration. The filtrate was evaporated under reduced pressure and the viscous residue was partitioned between 300 ml of 15% sodium hydroxide solution and 500 ml of ethyl ether. The organic layer was washed with 200 ml of 15% sodium hydroxide solution, 300 ml of water, dried (magnesium sulfate) and the solvent evaporated under reduced pressure to give 24.5 g (42%) of the title compound as a lightly colored viscous oil. the reaction mixture was heated at reflux for 2 hr The solids were removed by filtration The filtrate was evaporated under reduced pressure the viscous residue was partitioned between 300 ml of 15% sodium hydroxide solution and 500 ml of ethyl ether The organic layer was washed with 200 ml of 15% sodium hydroxide solution, 300 ml of water dried (magnesium sulfate) the solvent evaporated under reduced pressure
