実験手順

To a solution of ethyl 2-bromo-3-(3-cyanophenyl)-3-oxopropionate (0.60 g, 2.03 mmol) in 20 mL of absolute ethanol was added N-benzylthiourea (0.34 g, 2.03 mmol). The resulting mixture was stirred at 80° C. for 3 h. The reaction was allowed to cool and the solvent was evaporated in vacuo. The residue was taken up in ethyl acetate, washed with saturated aq NaHCO3 and brine, dried (MgSO4) and concentrated in vacuo to-yield a solid. Trituration with hexanes/ethyl ether left the title compound as an off-white solid (0.36 g, 49%). MS (ESI) 364.1 (M+H)+.
