Reaction Steps

A vial containing the title compound from Example 55 Step A [enantiomer B (0.647 g, 2.40 mmol)], bis(pinacolato)diboron (1.22 g, 4.79 mmol), tris(dibenzylideneacetone)dipalladium (0) (0.439 g, 0.479 mmol), tricyclohexylphosphine (0.269 g, 0.958 mmol) and potassium acetate (0.705 g, 7.19 mmol) in 1,4-dioxane (12 mL) was flushed with nitrogen, sealed tightly and heated to 80° C. overnight. The reaction was then passed through a syringe filter and concentrated under reduced pressure to provide the title compound: LCMS m/z 235.95 [M+H]+.
