실험 절차

(38) To a solution of benzaldehyde (295 mg, 2.77 mmol) and 2,6-dimethoxyacetophenone (500 mg, 2.77 mmol) in 4.1 ml of methanol was added 0.1 ml of 40% sodium hydroxide in water at 10° C. After stirring for 3 hour at room temperature, a solid appeared and was filtered. The precipitate was recrystallized from methanol to afford 371 mg (49.9%) of white flakes: mp 125.5-126.6° C. (lit. mp 123-124° C., Kuck and Grutzmacher, Org. Mass. Spect., 1978, 13, 90-102). 1H NMR (250 MHz) δ 7.55-7.51 (m, 2 H), 7.39-7.30 (m, 5 H), 7.00-6.94 (d, 1 H), 6.64-6.61 (d, 2 H), 3.79 (s, 6 H); 13C NMR (62.7 MHz) 213. 176.1, 163.9, 153.4, 149.4, 149.0, 147.4, 147.3, 147.0, 122.6, 74.5 ppm.
