Analyzing the synthesis route of 1-(3,4-Difluorobenzyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid

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. 1001413-01-9, 1-(3,4-Difluorobenzyl)-2-oxo-1,2-dihydropyridine-3-carboxylic acid, other downstream synthetic routes, hurry up and to see.

Synthetic Route of 1001413-01-9 ,Some common heterocyclic compound, 1001413-01-9, molecular formula is C13H9F2NO3, 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.

Thiophene-2-methanamine (0.562 g, 0.00496 mol; Acros) and l-(3,4-difluoro-benzyl)- 2-oxo-l,2-dihydro-pytauidine-3-carboxylic acid (1.32 g, 0.00496 mol) and N,N,N,N’-tetramethyl- O-(7-azabenzotriazol-l-yl)uronium hexafluorophosphate (2.08 g, 0.00546 mol; Applied Biosystems) was dissolved in N,N-dimethylformamide (15.0 mL, Acros). To this was added N,N-diisopropylethylamine (4.32 mL, 0.0248 mol; Acros) and the reaction was stirred overnight at room temperature. The reaction was evaporated to dryness, then partitioned between 5% citric acid, ethyl acetate. The organic layer was washed with saturated sodium chloride, dried with sodium sulfate, filtered and concentrated. The residue was purified on preparative HPLC. Appropriate fractions were combined and evaporated to give the product in 1.04 g yield. MS m/z= 361.06 M+H.
