Reaction Steps
To a solution of (1R)-1′-{[1-(4-bromophenyl)cyclobutyl]carbonyl}-3H-spiro[2-benzofuran-1,3′-pyrrolidin]-3-one (20.7 mg, 0.0000485 mol) and oxazolidin-2-one (12.7 mg, 0.000146 mol) in freshly distilled toluene (0.34 mL, 0.0032 mol), were added tris(dibenzylidene acetone)dipalladium(0) (4.4 mg, 0.0000048 mol), tri-tert-butylphosphine (2.0 mg, 0.0000097 mol) and cesium carbonate (15.8 mg, 0.0000485 mol), and the mixture was heated to 50° C. overnight. The reaction mixture then was cooled to rt, filtered over celite and concentrated under reduced pressure. The crude product was purified by prep-HPLC. LC/MS (M+H) 433.2.
