実験手順

A solution of 26.5 g (0.13 mole) of glycerol guaiacolate in 100 ml of methylene chloride and 10.8 ml (0.13 mole) of pyridine was added in a thin stream to a stirred solution of 17.1 g (0.13 mole) of N-methylsulfamoyl chloride in 70 ml of methylene chloride, and the reaction mixture was stirred at ambient temperature for 2 hr. The reaction mixture was treated with 150 ml of water, the layers were separated, and the organic layer was washed successively with a 200 ml portion of 2N hydrochloric acid solution, four 200 ml portions of water, dried (magnesium sulfate), and the solvent was evaporated under reduced pressure to yield a viscous oil. The oil was purified by preparative high pressure liquid chromatography. Fractions containing the desired product were combined and the solvents evaporated under reduced pressure to give 13.9 g (37%) of the title compound as a yellow gum.
