Participants

Reaction Steps

2,3-Dimethoxybenzaldehyde (0.84 g, 5.03 mmol), 1-bromo-3,5-dimethoxybenzene (1.20 g, 5.53 mmol), and n-butyl lithium (2.20 ml, 5.53 mmol) were treated in the same manner as described above for the synthesis of (2,3-dihydrobenzo[1,4]dioxin-6-yl)-(3,5-dimethoxyphenyl)methanol. The crude material was purified via flash column chromatography (10% EtOAc in hexane gradient to 50% EtOAc in hexane in about 40 min.) to give (2,3-dimethoxy-phenyl)-(3,5-dimethoxy-phenyl)-methanol as a greenish yellow oil (1.36 g, 89%): 1HNMR (CDCl3) 7.08-7.01 (m, 1H, Ar), 6.9 3-6.85 (m, 2H, Ar), 6.57 (d, J=2 Hz, 2H, Ar), 6.35 (t, J=2 Hz, 1H, Ar), 5.94 (d, J=6 Hz, 1H, CHOH), 3.86 (s, 3H, OCH3), 3.76 (s, 6H, 2OCH3), 3.66 (s, 3H, OCH3), 3.05 (d, J=6 Hz, 1H, OH). The product was carried over to the next step.
