実験手順

To a solution of 3-(1′-oxo-1′,3′,5,7,8,9-hexahydrospiro[benzo[7]annulene-6,2′-indene]-6′-yl)benzonitrile (31 mg, 0.086 mmol) in CH2Cl2 (2 mL) was added TiCl4 (66 mg). It was stirred in microwave at 50° C. for 5 minutes. Then bis-trimethylsilylcarbodiimide (112 mg, 0.6 mmol) was added. The resulting mixture was stirred in microwave at 60° C. for 10 minutes. The reaction mixture was poured into ice-water, extracted with DCM. The combined organic phases were dried over anhydrous Na2SO4, and filtered. The filtrate was concentrated to give N-(5′-(3-cyanophenyl)-5,7,8,9-tetrahydrospiro[benzo[7]annulene-6,2′-indene]-3′(1′H)-ylidene)cyanamide (50 mg, crude).
