Toluene → N-((S)-6-Pyridin-3-yl-1,2,3,4-tetrahydronaphthalen-2-yl)-4-[(S)-1-(tetrahydrofuran-2-yl)methoxy]benzamide

A mixture of N-((S)-6-bromo-1,2,3,4-tetrahydronaphthalen-2-yl)-4-[(S)-1-(tetrahydrofuran-2-yl)methoxy]benzamide (1.00 g), toluene (10 ml) and Pd(PPh3)4 (2.69 g) was admixed with 3-pyridylboronic acid (0.28 g), ethanol (3 ml) and cesium carbonate solution (1.2 ml; 2 M in water). The mixture was boiled at reflux for 7 hours. The cooled reaction mixture was diluted with ethyl acetate and washed with water. The organic phase was washed with sodium chloride solution, dried over sodium sulfate and concentrated. The residue was purified by chromatography on silica gel. The product was thus obtained with the molecular weight of 428.54 (C27H28N2O3); MS (ESI): 429 (M+H+).
