Computed Properties of C8H8FNO2

An aromatic amine 1d-2 (0.20 mmol), a platensimycin acid (0.10 mmol),2-(7-Azobenzotriazole)-N,N,N’,N’-tetramethyluronium hexafluorophosphate (HATU) (0.30 mmol) was added to the reaction flask and 1.0 ml was added.N,N-dimethylformamide, stirring at room temperature; slowly adding triethylamine (0.45 mmol), stirring for 12 hours, rotary evaporationSolvent to obtain a crude product, which is subjected to column chromatography to obtain a platensimycin analog2d-2, yield 43%.

The synthetic route of Methyl 5-amino-2-fluorobenzoate has been constantly updated, and we look forward to future research findings.
