Reaction Steps
To a solution of 4-[(3-bromo-2-ethylphenyl)methylidene]piperidine (D137) (1 g, 3.57 mmol) in Acetonitrile (10 mL) was added DBU (0.807 mL, 5.35 mmol) and ethyl 2-propenoate (0.429 g, 4.28 mmol). The reaction solution was heated to 60° C. for overnight. The solvent was removed in vacuo and the residue was diluted with ethyl acetate, washed with water, dried and concentrated to afford ethyl 3-{4-[(3-bromo-2-ethylphenyl)methylidene]-1-piperidinyl}propanoate (D138) (1.35 g), which was used directly without further purification. MS (ES): C19H26BrNO2 requires 379.1. found 380.1 (M+H+).
