Procedure
In a manner similar to that of Reference Example 3, 10 parts of 2-amino-5,6-dimethoxy-3,4-dihydro-1(2H)-naphthalenone hydrochloride is reacted with 300 volume parts of cyclopentanone. The procedure yields 10.2 parts of 2-cyclopentylamino-5,6-dimethoxy-3,4-dihydro-1(2H)-naphthalenone hydrochloride as colorless crystals melting at 158°-167° C (decomposition).
