実験手順
The product from Example 2 Part A (55.9 mg, 0.12 mmol) and (E)-4-(methylsulfonamido) styrylboronic acid (28.9 mg, 0.120 mmol) were reacted in the same manner as Example 2 Step B. The crude product was purified by silica gel flash chromatography eluting with ethyl acetate/hexane (5% to 25%) to give the title compound.
