実験手順

2-(4-methoxycarbonylphenyl)thiophene was prepared in the same manner as described in Example 32C from thiophene-2-boronic acid (1.0 g, 7.81 mmol) and methyl-4-bromobenzoate (1.68 g, 7.81 mmol). Purification by column chromatography using 2% ethyl acetate/hexanes gave 1.1 g of 2-(4-methoxycarbonylphenyl)thiophene as a white solid (65% yield).
