실험 절차
250 mg (0.8 mmol) of ethyl 2-(4-bromo-2-oxopyridin-1(2H)-yl)-3-cyclopropylpropanoate (racemate) and 214 mg (0.96 mmol) of 5-chloro-2-trifluoromethylphenylboronic acid in the presence of tetrakis(triphenylphosphine)palladium(0) were reacted according to General Method 2A. Yield: 35 mg (purity 87%, 9% of theory) of the title compound and 70 mg (22% of theory) of the product which is already hydrolysed (Example 6.1F)
