The title compound was obtained using the following procedure: The sulfamoyl chloride in acetonitrile solution prepared in (a) was reacted as in Example 12 with 10.5 g (0.0755 mole) of 1,7-heptanediol (95%), 30.3 g (0.300 mole) of triethylamine in 100 ml additional acetonitrile followed by using extracting, washing and concentration procedures of Example 12 through the first evaporation. The viscous residue which solidified on standing was purified by high pressure liquid chromatography using the Waters Associates® Prep LC/System 500A with Prep Pak 500 ® silica. Eluting solvent used was 10:1 mixture methylene chloride-acetone at a flow rate of 200 ml/min. Fractions containing the title compound were combined and the solvents were evaporated under reduced pressure to give a viscous oil which solidified on standing. The solid was recrystallized from wet methylene chloride to give 8.2 g (37% yield) of title compound as white solid, mp 88.5°-90.5° C.
