These common heterocyclic compound, 13194-68-8, name is 4-Iodo-2-methylaniline, 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. 13194-68-8
To a solution of 4-iodo-2-methyl-aniline (4.0 g, 17 mmol) and Pd(dppf)2Cl2 (140 mg, 0.17 mmol) in THF (50 mL) was added isopropylmagnisium chloride (25.5 mL, 51.0 mmol) at -78 C and was reacted at reflux for 4 h. The reaction was quenched with a saturated solution of NH4ci, extracted with EtOAc, dried over anhydrous Na2SC>4, filtered, and concentrated to dryness. The residue was purified by flash column chromatography to give the title compound as a brown solid (320 mg, 12%). MS (ESI): mass calcd. for ci0Hi5N, 149.1; m/z found, 150.0 [M+H]+.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 13194-68-8.
