The procedure described in Example 10B was followed using a mixture of 4-(2,2,2-trifluoro-1,1-dimethylethyl)phenyl trifluoromethanesulfonate (13.3 g, 40 mmol), potassium isopropenyltrifluoroborate (7.0 g, 47.6 mmol), PdCl2(dppf)-CH2Cl2 (1.6 g, 1.98 mmol) and triethylamine (5.5 ml, 40 mmol) in n-propanol (400 ml). The crude residue was applied to a silica gel chromatography column and eluted with a volume mixture of hexane and EtOAc (100/1) to afford 6.32 g (70% yield) of the title compound as a colorless oil.
