Paragraph 0025; 0026, (2017/03/08)
The invention relates to the field of fine chemical intermediates, in particular to a preparation method for 2-fluoro-3-chlorobenzaldehyde, namely, a fluorine-containing medical intermediate. According to the method, 2,3-dichlorobenzonitrile serves as raw materials, and 2-fluoro-3-chlorobenzaldehyde is obtained after fluorination, hydrolysis, oxidation and reduction are conducted. The method is low in raw material cost, high in apparent availability, mature and stable in reaction technology, high in operability and beneficial to industrial production.
