Procedure

The sulfamoyl chloride in acetonitrile solution prepared in (a) was reacted as in Example 12 with 12.2 g (0.1 mole) of β-phenethyl alcohol using 40.4 g (0.4 mole) triethylamine in 100 ml additional acetonitrile followed by using extracting, washing and concentration procedures of Example 12 through the first evaporation. The crude oily residue was purified by chromatography (10×80 cm glass column; 700 g silica gel; eluents methylene chloride followed by 10:1 methylene chloride/acetone). Fractions containing the title compound were combined and solvents evaporated under reduced pressure to give 13.6 g (68% yield) of title compound as light-yellow oil.
