Reaction Steps

A mixture of 1-[(1,2,3,4-tetrahydro-1-hydroxy-2-naphthalenyl)-methyl]-4-anilino isonipecotonitrile (5.0 g) and 90% sulfuric acid (60.0 g) is heated for 10 minutes at 70° C. The mixture is then stirred at room temperature for an additional hour. The reaction mixture is poured into ice-water, basified with ammonium hydroxide, and extracted with chloroform. Concentration of the dried chloroform solution followed by trituration with benzene yields the title compound.
