Procedure

To a solution of 6-isopropylpyridine-2-carboxylic acid (6-acetyl-3-methoxy-2-methyl-phenyl)amide (107, 0.70 g, 2.14 mmol) in pyridine (5 mL) were added 2.5 equivalents of freshly grounded KOH along with water (50 μL). The mixture was heated by microwave irradiation at 133° C. for 55 min, then 80-85% of the pyridine was evaporated under reduced pressure. The residue was poured on ice and neutralized with acetic acid. The precipitate was filtered off, then dried to give 0.62 g (95%) of the title compound 108 (1.8 g, 95%): m/z=309 (M+H)+.
