Procedure
(76) Cyclohexanone (10 mmol), 60 ml of ethanol, and 2,6-dichlorobenzaldehyde (20 mmol) were used. The reaction stirred for 4 hours. A solid formed and was filtered. Recrystallization from ethanol yielded 3.24 g (78.6%) of bright-yellow flakes: mp 185.0-186.0° C. (lit. mp 183° C., Smith et al., supra). 1H NMR (250 MHz) δ 7.60 (s, 2 H), 7.37-7.18 (m, 6 H), 2.45 (t, 4 H), 1.73 (p, 2 H); 13C NMR (62.7 MHz) 188.2, 140.3, 134.6, 134.4, 132.4, 129.6, 128.1, 28.4, 22.1 ppm.
