Conditions

Temperature: 100 °C

Procedure

Cesium carbonate (12.4 g), palladium (II) acetate (0.12 g), triethylamine (0.12 mL) and Xantphos (0.474 g) were suspended in dioxane (50 mL) under nitrogen. 2-Trifluoromethanesulfonyloxy-5,6,7,8-tetrahydronaphthalene-1-carboxylic acid methyl ester (Intermediate 7, 4.2 g) and benzhydrylidenamine (5.5 mL) in dioxane (35 mL) were added and the mixture was heated at 100° C. for 3.5 hours. The resulting mixture was partitioned between ethyl acetate and water. The organic solution was washed with water and concentrated under vacuum. The residue was recrystallised from methanol to give the title compound as an off-white solid (8.2 g).
