Adding a certain compound to certain chemical reactions, such as: 216393-66-7, name is 1,2,5-Trichloro-3-iodobenzene, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 216393-66-7, Application In Synthesis of 1,2,5-Trichloro-3-iodobenzene
General procedure: (S)-3-((R)-Hydroxyphenylmethyl)pyrrolidine-1-carboxylic acid t-butyl ester 11a (250 mg, 0.9 mmol), copper(I) iodide (51 mg, 270 mumol), 1,10-phenanthroline (97 mg, 540 mumol) and 2,4-difluoro-1-iodobenzene (216 muL, 1.8 mmol) were combined in a vial under air. Toluene (1.4 mL, 14 mmol) was added, followed by the addition of cesium carbonate (587 mg, 1.8 mmol). Air was bubbled through the mixture, the vial was sealed, and the mixture was heated at 105C for 48 hours. The mixture was filtered through Celite. The Celite was then rinsed with DCM (2 x 15 ml), and the resultant filtrate was concentrated. The resultant oil was treated with 1.25 M of HCl in EtOH (5.8 mL, 7.2 mmol) and stirred overnight. The mixture was concentrated and purified by reverse phase preparative HPLC (10 to 70% CH3CN in water with 0.5% TFA) to yield 76 mg (97% purity, 26% yield) of the title compound as the mono-TFA salt.
