In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 618-91-7 as follows. HPLC of Formula: C8H7IO2
To the mixture of methyl 3-iodobenzoate (157 mg, 0.60 mmol), potassium carbonate (166 mg, 1.20 mmol), cupper(I) iodide (14 mg, 0.07 mmol) and PdCi2(Ph3P)2 (21 mg, 0.03 mmol) in tetrahydrofuran (2 mL) was added tert-butyl propiolate (330 muL, 2.40 mmol) at room temperature. After stirred for 20 h at 60C, the mixture was evaporated to dryness. The residue was chromatographed on a silica gel (EtOAc:hexanes 0: 1~1 : 10) to give the title compound 9-1 (155 mg, 99% yield) as a light brown oil. 1H NMR (300 MHz, CDCl3) delta 8.25 (t, J= 1.4, 1H), 8.16 – 8.05 (m, 1H), 7.80 – 7.68 (m, 1H), 7.46 (t, J= 7.8, 1H), 3.93 (s, 3H), 1.55 (s, 9H).
According to the analysis of related databases, 618-91-7, the application of this compound in the production field has become more and more popular.
