Reaction Steps

N-Methyl-4-methanesulphonamidophenethylamine (1.66 g, 7.3 mmole) and 2-chloromethyl-3-methyl-5-nitrobenzofuran (see Preparation 7B--0.82 g, 3.6 mmole) were heated at reflux temperature in ethanol (20 ml) for 3 hours. The solvent was then evaporated and the residue was purified by column chromatography on silica eluting with methylene chloride/hexane (4:1) followed by methylene chloride containing methanol (0% up to 5%). The product-containing fractions were combined and evaporated, and the residue was recrystallised from ethanol to give the title compound, yield 1.52 g, m.p. 124°-124.5°.
