실험 절차

The product from Example 219a (0.20 g, 0.93 mmol) was reacted with phenylboronic acid (0.135 g, 1.11 mmol) for 19.5 h at 80° C. as described in Example 218a. The reaction mixture was cooled and filtered through celite, the filtrate concentrated under vacuum to give the crude product which was purified by flash chromatography on silica gel to give the title biphenyl (0.187 g, 94%) as a yellow oil.
