実験手順
A solution of 3-morpholin-4-yl-3-thioxopropanenitrile (0.122 g, 0.72 mmol) and p-anisaldehyde (0.1 mL, 0.86 mmol) in 10% piperidine/ethanol (5.5 mL) was allowed to stir at 50° C. under nitrogen for 3.5 h. The reaction mixture was concentrated and the residue was diluted with 10% citric acid solution and extracted with EtOAc. The organic solutions were combined, washed with sat NaHCO3 and brine, dried over MgSO4, filtered and concentrated to give 3-(4-methoxyphenyl)-2-(morpholin-4-ylcarbonothioyl)acrylonitrile. The crude product was a mixture of stereoisomers and was used directly in the next step. LCMS: (AA) ES+ 289.
