Reaction Steps
To a mixture of 2-hydroxybenzophenone (2.0 g, 10 mmol) and malononitrile (661 mg, 10 mmol) in ethanol (15 mL) was added piperidine (0.5 mL, 5.0 mmol). The mixture was stirred under 0-5° C. for 2 h. The solvent was evaporated and the residue was purified by chromatography on silica gel with ethyl acetate and hexane (1:2) as eluant, yielding 1.2 g (48%) of the title compound. 1H NMR (CDCl3): 7.74-7.29 (m, 7H), 7.20-7.13 (m, 2H).
