To a solution of 6-methylpyridine-2-carboxylic acid (6-acetyl-3-methoxy-2-methyl-phenyl)-amide (96) in pyridine (15 mL) was added 2.5 equivalent of freshly grounded KOH along with water (200 μL). The mixture was heated by microwave irradiation at 150° C. for 30 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 the title compound (1.8 g, 95%): m/z=299 (M+H)+.
