A mixture of N-((R)-5-bromoindan-2-yl)-5-[(S)-1-(tetrahydrofuran-2-yl)methoxy]pyridine-2-carboxamide (1.70 g), tributylvinyltin (1.55 g), triphenylphosphine (85.5 mg), palladium(II) acetate (18.3 mg) and DMF (20 ml) was admixed under argon with triethylamine (7.4 ml) and heated to reflux for 4 hours. After cooling, the reaction mixture was partitioned between water and ethyl acetate. The organic phase was dried over sodium sulfate and concentrated. The residue was filtered through silica gel. This afforded the product with the molecular weight of 364.45 (C22H24N2O3); MS (ESI): 365 (M+H+).
