실험 절차

Using the procedure of Example A-1, step 1, 4-pyridylacetone (step 1) (1 g, 7.4 mmol) was condensed with benzaldehyde (790 mg, 7.4 mmol) in benzene (15 mL) containing piperidine (50 mg) at reflux. The desired 4-phenyl-3-(4-pyridyl)-3-butene-2-one (1.3 g, 78%) was obtained as a crystalline solid: m.p. 101-103° C. Anal. Calc'd for C15H13NO (223.28): C, 80.69; H, 5.87; N, 6.27. Found: C, 80.59; H, 5.79; N, 6.18.
