Reference of 13194-69-9,Some common heterocyclic compound, 13194-69-9, name is 2-Iodo-5-methylaniline, molecular formula is C7H8IN, 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.
General procedure: A 25mL oven-dried Schlenk tube were added 2-iodoaniline 1a (110mg, 0.5mmol), phenylacetic acid 2a (81.7mg, 0.6mmol) or benzyl chloride 4a (75.9mg, 0.6mmol), selenium powder (118mg, 1.5mmol), CuBr (7.17mg, 10mmol%), KOH (56.1mg, 1.0mmol) or Cs2CO3 (326mg, 1.0mmol), DMSO (1.5mL). The tube was purged with nitrogen three times. Then the reaction mixture was stirred in a preheated oil bath at 120C for 18h. After the reaction was completed, the mixture was diluted with a saturated solution of Na2CO3 (15mL) and extracted with ethyl acetate (3×10mL). The organic layer was dried over anhydrous Na2SO4, then concentrated in vacuo. The residue was purified by silica gel column chromatography (petroleum ether/ethyl acetate, 100/1) to give pure product 3aa.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-Iodo-5-methylaniline, its application will become more common.
