実験手順

6-Nitro-1-hydroxy-2-(trifluoromethyl)-1H-imidazo(4,5-b)pyridine (4.9 grams) was mixed with 100 milliliters of ethanol and 3 milliliters of concentrated hydrochloric acid, and 1 gram of 5 percent palladium on carbon was added to the mixture. The mixture was hydrogenated to a 3 mole-equivalent uptake of hydrogen. The reaction mixture was then filtered and evaporated, yielding a gummy solid residue which was taken up in 150 milliliters of water and used directly in the reaction reported in the following example.
