Reaction Steps

A solution of 18-crown-6 ether (0.60 g) and benzene (60 mL) was heated under reflux with a water separator for 1 hour, then cooled to room temperature. 2-Chloromethyl-4-isopropyl-6-methoxysaccharin (3.03 g) and sodium azide (0.65 g) were added, and the mixture was stirred for a week at room temperature, then chromatographed on a column of silica gel (silica gel 60, 83 g) using benzene as eluant. The fractions containing the product, which were identified by thin layer chromatography, were combined and concentrated affording 2-azidomethyl-4-isopropyl-6-methoxysaccharin as a solution in benzene (250 mL).
