Procedure: Similarly, oxidation of N-(1,2,3,4-tetrahydro-1-naphthyl)acetamide with ceric ammonium nitrate, K2S2O8 /catalytic AgNO3, KMnO4 /catalytic ceric ammonium nitrate, t-butyl chromate, Na2Cr2O7, ceric sulfate, chromyl chloride and H2O2 /V2O5, respectively, under standard conditions and the general workup conditions described in Example 1, also affords the title compound.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 1,2,3,4-Tetrahydro-1-naphthylamine is stirred with acetic anhydride to afford N-(1,2,3,4-tetrahydro-1-naphthyl)-acetamide, which is oxidized to N-(1,2,3,4-tetrahydro-4-oxo-1-naphthyl)acetamide by the method of Example 1.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The reaction was carried out in the same manner as in Example 1-(1), except that 200 mg of the compound prepared in (1) above was used instead of 1-acetylaminotetraline of Example 1-(1). The reaction product was post-treated to produce 55 mg of the title compound. The reaction product was post-treated

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 10 gm of 1-acetylamino-tetraline was dissolved into a mixed solvent of 400 ml acetone and 40 ml of 15% aqueous solution of magnesium sulfate. The solution was kept at 0° C. to add 42 gm of potassium permanganate, followed by stirring for 20 minutes at the same temperature. 800 ml of water was added to the residue obtained by concentrating the solvent. Precipitates thus obtained was extracted with chloroform and the extract was washed with brine and dried over magnesium sulfate. The residue obtained by the concentration of the solvent was subjected to silica gel column chromatography using chloroform as an eluant to obtain fractions containing the target compound. The fractions were concentrated to produce 5.46 gm of the title compound. was kept at 0° C. obtained by concentrating the solvent Precipitates thus obtained was extracted with chloroform the extract was washed with brine dried over magnesium sulfate The residue obtained by the concentration of the solvent to obtain fractions containing the target compound The fractions were concentrated
