Reaction Conditions

Temperature	100 °C

Reaction Steps

4-Chloro-7-azaindole (119, 100 mg, 0.66 mmol, prepared as described in Example 70, Scheme 81), 2-Benzofuranboronic acid (212 mg, 1.31 mmol) and Potassium fluoride (127 mg, 2.18 mmol) were stirred in 3 mL of anhydrous dioxane. Tris(dibenzylideneacetone)dipalladium(0) chloroform adduct (10.2 mg, 9.83E-3 mmol) and tri t-butylphosphine (6.6 mg, 0.033 mol) were added and the suspension was stirred at 100° C. for 4 hours in a pressure tube under inert atmosphere. The reaction mixture was cooled to room temperature and was adsorbed onto silica gel and purified by chromatography to provide the compound (120, 56 mg, 36%). MS (ESI) [M+H+]+=235.20.
