반응 단계
To a solution of 4-bromo-2-fluorobenzaldehyde (1.02 g, 4.83 mmol) in DMSO (4 mL), was added ethyl 2-mercaptoacetate (0.58 mL, 5.31 mmol), followed by Et3N (1.35 mL, 9.65 mmol), and the mixture was heated at 80° C. for 3 h. The resulting dark mixture was poured into water (50 mL) and extracted with EtOAc (2×50 mL). The combined organic extracts were washed with 10% NaCl, dried over anhydrous Na2SO4, filtered and concentrated in vacuo to give the title compound as a light yellow waxy solid (1.29 g, 94%).
