Reaktionsschritte

To a solution of (1R)-1′-{[1-(4-bromo-2-fluorophenyl)cyclopropyl]carbonyl}-3H-spiro[2-benzofuran-1,3′-pyrrolidin]-3-one (30 mg, 0.00007 mol, this compound was prepared by using a method that was analogous to that used for the synthesis of 238) in tetrahydrofuran (0.2 mL, 0.002 mol) were added tris(dibenzylideneacetone)dipalladium(0) (3 mg, 0.000003 mol), ti-tert-butylphosphine (1.7 mg, 0.0000083 mol), 4-(tributylstannyl)pyridine (30.7 mg, 0.0000835 mol), and the mixture was heated to 120° C. under microwave for 30 minutes. The reaction mixture was then filtered and the filtrate was diluted with methanol, and the product was isolated and purified by prep-HPLC. LC/MS (M+H+) 429.2.
