Reaktionsschritte

A suspension of (1H-benzo[d]imidazol-2-yl)(4-(3-bromopyridin-2-yloxy)phenyl)methanone (500 mg, 1.268 mmol), 2-cyclopenten-1-one (0.410 mL, 5.07 mmol), 105° C. and bis(tri-tert-butylphosphine)palladium (0) (64.8 mg, 0.127 mmol) in Dioxane (4 mL) was capped, degassed and backfilled with argon. The reaction was heated at 105° C. After 6 h, the reaction was cooled to 23° C., concentrated in vacuo and purified by silica gel chromatography (eluant: 40-100% EtOAc/hexane), affording the product as a yellow solid. MS (ESI, pos. ion) m/z: 396.1 (M+1). IC50 (uM) +++++.
