Procedure

6-Methyl-2-oxo-1-(3-trifluoromethyl-phenyl)-1,2-dihydro-pyridine-3,5-dicarboxylic acid 5-amide 4-methanesulfonyl-benzylamide (see Example 60, 0.05 g, 0.098 mmol), 3-bromo-2-butanone (0.020 g, 0.20 mmol), CaCO3 (0.015 g, 0.15 mmol), NMP (1.5 ml) and a magnetic stirrer bar were placed in a tube designed for microwave synthesis. The vial was sealed and the mixture was heated in a CEM Discover Microwave apparatus (100 W, 140° C.) for 2 h. The reaction was stopped and the crude mixture was dissolved in acetonitrile (2 ml) and water (2 ml) and was purified directly on preparative HPLC, giving the title compound (0.007 g, 13%) as a slightly brownish solid after freeze-drying the pure fractions.
