Reference of 349-75-7 ,Some common heterocyclic compound, 349-75-7, molecular formula is C8H7F3O, 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: To a 100 mL two-necked flask was added substituted benzylalcohol or 4,6-dimethylpyrimidine-2-thiol (2.60 mmol), NaOH (6.40 g, 1.60 mmol) and dimethylsulfoxide (30 mL). The flask was vacuumed and flushed three times with nitrogen. Then the solutionof 8 (0.20 g, 0.87 mmol) in dimethylsulfoxide (510 mL) was added, and the resulting mixture was heated to 80 C and kept at that temperature for approximately 12 h until the completion of the reaction (monitored by TLC). Subsequently, the mixture was cooled to room temperature and diluted with ethyl acetate (100 mL). The mixture was washed with brine to pH 7, and the organic phase was dried with anhydrous sodium sulfate. The organic phase was concentrated to get crude product, which was purified by column chromatography (ethyl acetate/ petroleumether 1:30 as eluent) to get 4a-ac in yields of 27.3-75.1%.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 349-75-7, (3-(Trifluoromethyl)phenyl)methanol, other downstream synthetic routes, hurry up and to see.
