実験手順
(4-Methoxybenzyl)-3,4-methylenedioxy-6-methoxybenzene was prepared from 6-(4-methoxybenzyl)-3,4-methylenedioxyphenol (L. Jurd, Tetrahedron, Vol. 33, pp. 163-168 (1977) by methylation as described above in H. Colorless prisms were obtained from benzene-solve F, m.p. 56°-57° (Found: C, 70.5; H, 5.95. Calc. for C16H16O4 : C, 70.6; H, 5.92%); pmr spectrum: δ3.74, 3H, S; δ3.77, 3H, S; δ3.82, 2H, S; δ5.85, 2H, S; δ6.52, 1H, S; δ6.55, 1H, S; δ6.80, 2H, D (J=9 Hz); δ7.11, 2H, D (J=9 Hz).
