Reference of 94087-40-8, These common heterocyclic compound, 94087-40-8, name is 3-Chloro-2-fluorobenzonitrile, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: An oven-dried round bottomed flask (50 mL capacity) equipped with a magnetic stir bar was evacuated and purged with argon. 2-Aminopyridine (1 mmol, 1 euiv), 2-fluorobenzonitrile (1.2 mmol, 1.2 euiv), KtOBu (4 mmol, 4 euiv) and DMSO (5 mL) were added successivelyat room temperature and the reaction mixture was allowed to stir at room temperature for 12 h. Water (10 mL) was added to the reaction mixture and the organic layer was extracted with ethyl acetate (2×20 mL). The combined organic phases were washed with brine and dried over sodium sulfate. The solvent was removed and the residue was purified by column chromatography on silica gel using hexanes/ethyl acetate as an eluent.
The synthetic route of 94087-40-8 has been constantly updated, and we look forward to future research findings.
