4-Chloro-2-(ethylsulfonyl)-6-methyl-benzonitrile (0.43 g, 1.77 mmol), morpholine (0.46 ml, 5.31 mmol) and potassium carbonate (0.32 g, 2.30 mmol) are taken up in N-methyl-2-pyrrolidone (3 ml) in a sealed tube and the resulting mixture is heated at 150° C. for 2 d. The mixture is then diluted with water (6 ml) and extracted with ethyl acetate (3×10 ml). The organic layer is washed with water (2×10 ml), brine (20 ml), dried over anhydrous sodium sulfate and evaporated to get the crude product, which is purified by column chromatography (silica gel, 25% ethyl acetate/hexane) to yield 2-(ethylsulfonyl)-6-methyl-4-morpholin-4-yl-benzonitrile (0.50 g, 1.70 mmol, 96%).
