실험 절차
To (3,4-difluoro-phenyl)-acetic acid (2.0 g) dissolved in 1,2-dichloroethane (5 mL) was added thionyl chloride (5 mL) and the mixture was refluxed for 16 hours under argon. The crude mixture was concentrated in vacuo to furnish 2.2 g (100%) of the title compound as a yellow oil. 1H NMR (500 MHz, CDCl3): 4.10 (s, 2H), 7.00 (m, 1H), 7.11 (m, 1H), 7.17 (m, 1H).
