Synthetic Route of 618-91-7,Some common heterocyclic compound, 618-91-7, name is Methyl 3-iodobenzoate, molecular formula is C8H7IO2, 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.
3-((E)-2-benzyloxycarbonyl-2-tert-butoxycarbonylamino- vinyl)-benzoic acid methyl ester: To 84A (10 g, 0.036 mol) dissolved in DMF (100 mL) were added methyl 3-iodobenzoate (9.5 g, 0.036 mol), palladium acetate (0.25 g, 1.08 mmol), tetrabutylammonium chloride (H g, 0.039 mol), and triethyl amine (15 mL, 0.108 mol). The mixture was flushed with nitrogen for 1 h, then heated at 85 0C overnight. The reaction mixture was diluted with brine and extracted with ethyl acetate. The organic layer was washed with brine and concentrated. The crude product was purified by flash chromatography on silica gel eluting with 10% ethyl acetate in petroleum ether to give 84B (10 g, 67.5%).
The synthetic route of 618-91-7 has been constantly updated, and we look forward to future research findings.
