반응 단계

The mixture of thioacetamide (16.0 g, 213 mmol) and 2-bromo-1-(4-methoxy-phenyl)-ethanone (4.0 g, 17.5 mmol) was heated at 140° C. for 24 h under nitrogen atmosphere. After the completion of the reaction mixture (TLC monitoring), water (100 mL) was added and extracted with ethyl acetate (3×100 mL). The combined organics was washed with water, brine, dried (Na2SO4), filtered and concentrated. The crude residue was purified over silica gel (230-400 M, 1% EtOAc-Hexane) to get the desired product (2.5 g, 69%).
