5.0 grams of the thus prepared 1,3-dimethyl-3-ethyl-2-methylene-1,7-diazaindane product were added to about 80 milliliters of ethanol and warmed in a 100 milliliter round bottom flask. When the internal temperature of the flask contents reached 60° C., 3.3 grams of 2-nitroso-3,5-dimethoxyphenol were added to the flask. The mixture was allowed to reflux overnight. The reaction mixture was allowed to cool down and a silica gel column was used to isolate the desired product, i.e., 1',3'-Dihydro-1',3'-dimethyl-3'-ethyl- 5,7-dimethoxyspiro-[2H-1,4-benzoxazine-2,2'-[2H]pyrrolo[2,3-b]pyridine]. Identification was confirmed by appropriate spectral analysis.
