Procedure

12.9 g (52.3 mmol) of m-chloroperbenzoic acid (70% purity) were added over a period of 15 minutes to a suspension of 10.21 g (52.3 mmol) of 2-isopropyl-6-methylthiomethylaniline [prepared as described in step (i) above] and 5.31 g (50 mmol) of sodium carbonate in 200 ml of methylene chloride, whilst ice-cooling. The reaction mixture was stirred for 1.5 hours at the same temperature, after which it was diluted with methylene chloride, and the diluted mixture was washed with a saturated aqueous solution of sodium hydrogencarbonate, with an aqueous solution of sodium sulfite and with water, in that order. The solvent was then removed by distillation under reduced pressure, and the resulting residue was recrystallized from a mixture of diethyl ether and diisopropyl ether, to give 7.74 g of the title compound as a first crop. The mother liquor was then concentrated by evaporation under reduced pressure, and the concentrate was repeatedly recrystallized from the same solvent to give a further 0.75 g of the title S-oxide derivative. The total yield was 8.49 g (yield 77%). The title compound melted at 91°-91.5° (after recrystallisation from a mixture of methylene chloride and diisopropyl ether).
