実験手順

Methyl 2-[4-(bromomethylene)phenyl]benzoate (1.22 g, 0.04 mole), phthalimide (0.59 g, 0.04 mole), and potassium carbonate (0.55 g, 0.04 mole) are combined in 120 mL acetonitrile. The mixture is heated at reflux for 24 hours. At that time the mixture is filtered through celite and rotovapped to a residue. The residue is crystallized from ethyl acetate to afford 1.1 g (71%) of the title compound as a tan solid mp 148°-150° C. 1H NMR (CDCl3) 7.9-7.1 (12H, m); 4.92 (2H, s); 3.63 (3H, s). Mass Spec. (DCl) m/z 372 (M+H). Analysis--calc'd for C23H17NO4.1/2 H2O: C, 72.62; H, 4.77: N, 3.68; found: C, 72.88; H, 4.55; N, 3.77.
