Procedure

This compound was prepared according to the procedure used in Example 112. Thus, a mixture of 14.8 g (0.1 mole) of 2-phenoxyethanol (Matheson, Coleman, and Bell), 15.6 g (0.12 mole) of methylsulfamoyl chloride and 12.3 g (0.12 mole) of triethylamine in 150 ml of acetonitrile gave a viscous oil that solidified upon standing. The solid was recrystallized from benzene-petroleum ether (30°-60° C.) to yield 15.4 g (67%) of shiny, white flakes, mp 66°-68° C.
