5-(2-Bromopropanoyl)-6-methyl-N-[4-(methylsulfonyl)benzyl]-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2-dihydropyridine-3-carboxamide (Example 53 (b), 0.04 g, 0.067 mmol), thiourea (0.0067 g, 0.086 mmol), NaOAc (0.011 g, 0.136 mmol), EtOH (2 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, 90° C.) for 20 minutes, giving complete conversion of the starting material to a single product according to LC-MS. The solvents were evaporated to give a crude mixture which was purified on preparative HPLC, giving the title compound (0.026 g, 66%) as a slightly yellowish solid after freeze-drying the pure fractions.
