実験手順

In a manner similar to that of Example 1(h), by reaction of 4.6 g (25 mmol) 3-methoxymethoxyphenylboronic acid (described in Example 1(g)) and 5 g (22.8 mmol) of 1-(4-bromo-2-thiophenyl)-1-propanone with 22.8 mL of 2.0M potassium carbonate and 1.32 g of tetrakis(triphenylphosphine)palladium, followed by deprotection in methanol, the desired product is obtained in the form of a white solid (m.p.=112° C.; m=3.87 g: Y=73%).
