Reaction Steps

To a mixture of 1.0 grams (4.85 mmol) of the pyridone and 6.6 grams (48.5 mmol, 10 eq) of sodium acetate in 50 mL of ethanol was added 1.27 grams (4.85 mmol, 1 eq) of 4-diazo-N,N'-diethylaniline tetrafluoroborate. The reaction mixture turned blue immediately upon addition of the diazo compound. The mixture was stirred at room temperature for two hours and 50 mL of water was added. The blue solid was collected and washed with water and dried. This material was recrystallized from approximately 200 mL of ethanol to give 1.2 grams (65% yield) of the desired product. This material decomposes at 180°-185° C. with effervescence.
