반응 단계

4-Acetylbenzonitrile (44al, 1.00 g, 6.9 mmol), sodium hydroxide (0.40 g, 10.0 mmol) and water (20 ml) were combined in ethanol (20 ml) and stirred for 15 min at room temperature. Benzaldehyde (1b, 0.70 ml, 6.9 mmol) was added and the mixture stirred for 2 hr at room temperature. The resulting mixture was filtered and recrystallized from ethanol to give 1.46 g (91%) of a yellow solid: mp 120° C. [expected mp 119-120° C.]; 1H NMR: δ 7.34 (m, 3H), 7.62 (m, 2H), 7.80 (m, 4H), 8.06 (d, 2H, J=8.1 Hz); 13C NMR: δ 115.9, 117.9, 121.1, 128.6, 128.8, 129.0, 131.0, 132.4, 134.3, 141.4, 146.4, 188.9.
