실험 절차

In a manner similar to that of Example 1(h), by reaction of 1.61 g (8.7 mmol) of 4-methoxymethoxy-phenylboronic acid and 1.8 g (9.7 mmol) of 4-bromo-3-methylbenzoic acid with 26.7 mL of 2.0M potassium carbonate and 1.54 g of tetrakis(triphenylphosphine)-palladium, followed by deprotection-esterification in methanol, the desired product is obtained in the form of a colourless oil (m=2.06 g; Y=98%).
