Reaction Steps
In a manner similar to that of Reference Example 4, 5.16 parts of 2-cyclobutylamino-5,6-dimethoxy-3,4-dihydro-1(2H)-naphthalenone hydrochloride is hydrolyzed in a mixture of 75 volume parts 48% hydrobromic acid and 15 volume parts acetic anhydride. The procedure yields 4 parts of 2-cyclobutylamino-5,6-dihydroxy-3,4-dihydro-1(2H)-naphthalenone hydrobromide. Melting point: 229°-240° C (decomposition).
