반응 단계
Add zinc dust (1.18 g) to a suspension of 2,3-dichloro-5-trifluoromethyl-pyridine (2.0 g, 9.30 mmol) in 80:20 water and acetic acid (5 mL) and stir at 90° C. for 1 h. Add more zinc dust (1g) and stir at 90° C. for an additional 15 min. Cool the reaction mixture to room temperature, filter, and wash with dichloromethane. Carefully concentrate and purify the residue by silica gel chromatography, eluting with 100:0 to 0:100 hexane:dichloromethane, to obtain the title compound as a volatile oil (0.120g, 7%).
