실험 절차

4-(p-methoxyphenyl)butanoic acid (Compound 13, R1 =H, R2 =CH3) is treated with polyphosphoric acid (PPA) to form 7-methoxytetralone via Friedel-Crafts acylation (Compound 1, R1 =H, R2 =CH3 on C7. ##STR19## The tetralone (Compound 1) is then reacted with N-butylnitrite and potassium ethoxide to yield 2-hydroxyimino-7-methoxy-1-tetralone (Compound 2, R2 =CH3 on C7.
