1 65 g.(0.01 mole) of the nitrile in a mixture of 20 g. of concentrated sulfuric acid and 10 ml. of water was refluxed for one and two-thirds hours. A crude product was obtained by diluting the reaction mixture with water, neutralizing the sulfuric acid with strong aqueous sodium hydroxide and cooling to 5'. Recrystallization from 50 ml. of water gave an analytically impure sample in the form of short, light tan needles which sintered at 246" and melted at ...
