Reaction Steps
3-Amino-5,5-dimethyl-2-cyclohexen-1-one was reacted with 5-methyl-2-thiophenecarboxaldehyde 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-(5-methyl-2-thienyl)-1,8(2H,5H)-acridinedione. Crystallization from ethyl acetate/methanol gave a beige crystalline solid of melting point 266-268° C. (decomposition).
