Procedure

To a solution of (1R)-1′-({1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]cyclopropyl}carbonyl)-3H-spiro[2-benzofuran-1,3′-pyrrolidin]-3-one (130 mg, 0.00029 mol) in 1,4-dioxane (1 mL, 0.01 mol) were added 5-bromo-2-fluoropyridine (0.060 mL, 0.00058 mol), tris(dibenzylideneacetone)dipalladium(0) (1 mg, 0.000001 mol), tri-tert-butylphosphine (0.71 mg, 0.0000035 mol) and potassium fluoride (56 mg, 0.00096 mol). The mixture was heated at 110° C. under nitrogen for 30 minutes. The mixture was diluted with ethyl acetate, washed with water and brine successively, dried and concentrated. The product was purified by CombiFlash using CH2Cl2/EtOAc (max. EA 30%). LC-MS: 429.2 (M+H+)
