Reaction Steps
This compound was prepared by the procedure used to synthesize 2-(4-methylphenoxy)ethanol sulfamate in Example 33. Thus, 13.2 g (0.0794 mole) of 2-methyl-2-phenoxypropanol was reacted with sulfamoyl chloride prepared from 26.5 ml (0.298 mole) of chlorosulfonyl isocyanate (98%, Aldrich), 33.9 g (0.336 mole) of triethylamine, and 5.3 g (0.294 mole) of water in 250 ml of acetonitrile. The 12.4 g of a viscous, oily residue obtained was purified by high pressure liquid chromatography (Waters Associates Prep LC/System 500A; PrePAK 500® silica; methylene chloride), then by chromatography (4.5×90 cm glass column; 500 g of silica gel; methylene chloride). Fractions containing title compound were combined and the solvent was evaporated under reduced pressure to give 5.4 g (28%) of a viscous oil.
