Reaction Steps

3-Amino-5,5-dimethyl-2-cyclohexen-1-one was reacted with pyridine-4-carboxaldehyde 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-(4-pyridyl)-1,8(2H,5H)-acridinedione. Crystallization from dimethylformamide/water gave a pale yellow crystalline solid of melting point 218-219° C. (decomposition).
