Reaction Steps
α-(2-benzo[b]thienyl)-4-methyoxybenzyl alcohol was prepared by the method of Example 40A with benzo[b]thiophene (7.5 mmoles. 1.0 g), t-BuLi (1.7 m, 10.4 mmoles, 6.1 ml), 4-methoxy-benzaldehyde (8.9 mmoles, 1.1 ml) and THF (20 ml). Flash chromatography (20% ethyl acetate/hexanes) provided 1.75 g (87%) of a yellow solid.
