Reaction Steps

A mixture of 5-chloro-N-[3-fluoro-4-(pyridin-4-yl)phenyl]-2-hydroxybenzamide (compound of Reference Example 186; 0.104 g, 0.303 mmol), platinum(IV) oxide (0.100 g, 0.440 mmol) and methanol (10 ml) was stirred under ice cooling for 5 hours under hydrogen atmosphere. The reaction mixture was filtered, and the residue obtained by evaporation of the solvent of the filtrate under reduced pressure was purified by column chromatography on silica gel. 2N Hydrochloric acid was added to the obtained purified substance, and the mixture was refluxed for 1 hour. The solvent was evaporated under reduced pressure to give the title compound (0.021 g, 18%) as a colorless solid.
