3-Amino-5,5-dimethyl-2-cyclohexen-1-one was reacted with 3-(4-pyridyloxy)-benzaldehyde dimethyl acetal in an analogous manner to that described in Example 1 to give 3,4,6,7,9,10-hexahydro-3,3,6,6-tetramethyl-9-[3-(4-pyridyloxy)-phenyl]-1,8(2H,5H)-acridinedione. Purification by column chromatography on silica gel using dichloromethane/methanol (95:5) as the eluent gave a beige solid of melting point 186-188° C.
