Reaction Steps

To a solution of 3-(4-methoxy-1′-oxo-1′,3′-dihydrospiro[cyclohexane-1,2′-indene]-6′-yl)benzonitrile (30 mg, 0.09 mmol) in CH2Cl2 (3 mL) was added TiCl4 (0.2 mL). It was stirred in microwave at 50° C. for 5 minutes. Then bis-trimethylsilylcarbodiimide (0.2 mL, 0.146 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 (E)-N-(5′-(3-cyanophenyl)-4-methoxyspiro[cyclohexane-1,2′-indene]-3′(1′H)-ylidene) cyanamide (30 mg, crude).
