실험 절차

In a manner similar to that of Example 11(d), by reaction of 1.5 g (7.6 mmol) of 3-methoxymethoxy-2-methylbenzene-1-boronic acid (described in Example 11(c)) with 2 g (6.4 mmol) of methyl 3,5-dimethyl-4-trifluoromethanesulphonyloxybenzoate, 7.7 mL of 2.0M potassium carbonate solution and 370 mg (0.32 mmol) of tetrakis(triphenylphosphine)palladium, followed by deprotection in methanol, the desired product is obtained in the form of a white solid (m.p.=149° C.; m=1.34 g; Y=67%).
