実験手順
The product from Example 1 Part A (0.185 g, 0.501 mmol) and 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1,5-difluorobenzene (0.120 g, 0.501 mmol) were reacted in the same manner as Example 1 Part B for 16 hours. The crude product was purified on an Isco 12 g silica cartridge eluting with 5% ethyl acetate in hexane to give the title compound.
