Reaction Steps

A solution of 4-[[3-[ethyl[3-(propylthio)propyl]amino]-2-hydroxy-propyl]amino]-benzonitrile (2.0 g, 5.9 mmol) and toluene-4-sulfonic acid (2.3 g, 11.9 mmol) in ethanol (50 ml) was stirred 1/2 h at room temperature. The mixture was cooled to -10 ° C. and solid 3-chloroperbenzoic acid was added during 1/2 h. The solution was stirred for 1 h at room temperature. Solid calcium hydroxide (1.2 g, 16.4 mmol) was added, followed by stirring for 15 minutes. Filtration and evaporation gave an oily residue. Purification by column chromatography on silica gel yielded 1.0 g of the title compound.
