実験手順

Prepared by general procedure B(iii) but using 3-(2-bromocyclopent-1-enyl)-5-methylbenzoic acid ethyl ester instead of 3-(2-bromo-cyclopent-1-enyl)-6-methyl benzoic acid ethyl ester and using [5-trifluoromethyl-2-(2,4-di-fluorobenzyloxy)phenyl]boronic acid instead of (5-chloro-2-benzyloxyphenyl)boronic acid.
