Procedure
A mixture of C-(4-bromophenyl)-N-(2,4-dimethoxybenzyl)methanesulfonamide (1 g), morpholine (0.3 ml), Pd2(dba)3 (51 mg) and cesium carbonate (1.3 g) in dioxane was stirred at 80° C. for 16 h. The mixture was diluted with ethyl acetate, washed with water, dried over magnesium sulfate and concentrated. This was followed by purification by column chromatography (ethyl acetate/heptane). This gave the product (267 mg) with a molecular weight of 406.5 g/mol (C20H26N2O5S).
