Procedimiento

A solution of 4-(4-methylamino-3-nitro-phenoxy)-pyridine-2-carboxylic acid (2-hydroxy-ethyl)-amide (1 eq) and 10% palladium on carbon (0.1 eq) in methanol was stirred at room temperature and flushed with nitrogen. Hydrogen was flushed through the reaction for 1-2 hours or until the reaction was determined to be complete by HPLC. Nitrogen was flushed through the reaction for 15 minutes before the reaction was filtered through a celite pad. The celite pad was washed with excess methanol before it was all removed by evaporation under reduced pressure to afford the product as a light yellow solid. LCMS m/z 303.2 (MH+), tR=1.5 min.
