Reaction of 3-amino-5,5-dimethyl-2-cyclohexen-1-one with 3-(2-pyrazinyloxy)-benzaldehyde dimethyl acetal in an analogous manner to that described in Example 1 gave 3,4,6,7,9,10-hexahydro-3,3,6,6-tetramethyl-9- [3-(2-pyrazinyloxy)phenyl]-1,8-(2H,5H)-acridinedione. Crystallization from dimethylformamide/water gave a pale brown crystalline solid of melting point 204-207° C.
