58313-23-8, name is Ethyl-3-iodobenzoate, belongs to iodides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: Ethyl-3-iodobenzoate
Synthesis of 3-[2-Oxo-3-(l-phenyl-ethylidene)-2,3-dihydro-indol-l-yl]-benzoic acid ethyl ester; A Schlenk tube was charged with Cul (9.6 mg, 0.050 mmol, 5.0 mol %), 3-(l-Phenyl- ethylidene)-l,3-dihydro-indol-2-one (352.7 mg, 1.5 mmol), and K2C03 (276 mg, 2.0mmol), evacuated, and backfilled with argon. N, TV-Dimethylethylenediamine (11 uL, 0.10 mmol, 10 mol %), ethyl 3-iodobenzoate (278.8 mg, 1.01 mmol), and acetonitrile (1.5 ml) were added under argon. The Schlenk tube was sealed with a Teflon valve and the reaction mixture was stirred at 80 C for 23 h. HPLC monitor the reaction finished. Remove the solvent under reduced pressure. The residue was separated by flash chromatography column(gradient elution, 5-10% ethyl acetate in petroleum ether) to give 3-[2-Oxo-3-(l- phenyl-ethylidene)-2, 3 -dihydro-indol-l-yl] -benzoic acid ethyl ester as yellow powder (344 mg, 90%). 1H NMR (400 MHz, CDC13) 5ppm 1.42 (t, j=7.20 Hz, 3 H) 2.87 (s, 3 H) 4.42 (q, J=7.07 Hz, 2H) 6.25 (d, J=7.58 Hz, 1 H) 6.68 – 6.78 (m, 2 H) 7.09 (t, j=7.71 Hz, 1 H) 7.34 – 7.40 (m, 2 H) 7.47 – 7.58 (m, 3H) 7.62 – 7.72 (m, 2 H) 8.11 – 8.19 (m, 2 H) . MS calcd. for C25H2iN03 383, obsd. (ESf) [(M+H)+] 383.9.
