These common heterocyclic compound, 1194-02-1, name is 4-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. HPLC of Formula: C7H4FN
General procedure: General Procedure for Preparation of Tetrazoles in Water(Method II). TBAHS (0.25 mmol) was added to a mixture of nitrile (1 mmol), sodium azide (1.5 mmol), and 2 mL H2O in around-bottomed flask. The reaction mixture was heated to 85 C. After completion of the reaction (as monitored by TLC), the crude reaction mixture was transferred into a separatory funnel, to which was added 1 N HCl (15 mL) extracted by ethylacetate (EtOAc, 10 mL × 5). The combined organic layers were washed with H2O and dried over anhydrous sodium sulfate, and were evaporated under reduced pressure to give pure 5-substituted-1H-tetrazole.
The synthetic route of 4-Fluorobenzonitrile has been constantly updated, and we look forward to future research findings.
