Conditions

Temperature: 80 °C

Procedure

To a solution of 4-(3-iodo-benzyl)-morpholine (3.44 g, 11.4 mmol) in N,N-dimethylformamide (20 mL) was added triethylamine (1.7 mL, 12.5 mmol), ethyl acrylate (4.1 mL, 45.4 mmol), tri-o-tolylphosphine (346 mg, 1.14 mmol) and palladium (II) acetate (127 mg, 0.57 mmol). The mixture was heated at 80° C. overnight. After concentration, the mixture was chromatographed on silica gel to afford Intermediate 172(a) as a colorless oil (2.37 g, 9.1 mmol) in 80% yield.
