N-(4-Bromo-naphthalen-1-yl)-3-fluoro-5-morpholin-4-yl-benzamide (2.5 g, 5.8 mmol), 1-hexenyl boronic acid (1.06 g, 8.3 mmol), cesium carbonate (3.04 g, 9.34 mmol) and tetrakis triphenylphosphine palladium(0) (100 mg) in dioxane (22 ml) are heated to 100° C. under nitrogen for 24 hours. The mixture is then poured into ethyl acetate (200 ml) and washed with water (2×100 ml). The organic layer is dried over anhydrous sodium sulfate and evaporated to dryness to give 3-fluoro-N-(4-hex-1-enyl-naphthalen-1-yl)-5-morpholin-4-yl-benzamide as a brown solid (2.7 g).
