444-29-1, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 444-29-1, name is 1-Iodo-2-(trifluoromethyl)benzene, This compound has unique chemical properties. The synthetic route is as follows.
To a solution of [9-((1R,2R,4R,5R)-4-ethynyl-7,7-dimethyl-3,6,8-trioxabicyclo[3.3.0]oct-2-yl)purin-6-yl]cyclopentylamine (40 mg, 0.12 mmol), a compound of formula (5), in tetrahydrofuran (4 ml) under nitrogen was added catalytic amounts (3 mg) of dichlorobis(triphenylphosphine)palladium(II) and copper(II)iodide, followed by 1-iodo-2-trifluoromethylbenzene (0.25 ml, 0.3 mmol). Triethylamine (0.4 ml) was then added, and the mixture stirred for 15 minutes at room temperature. The solvent was removed under reduced pressure, and the residue was purified by preparative TLC, eluding with methanol:methylene chloride (6.5:1), to yield [9-((1R,2R,4R,5R)-7,7-dimethyl-4-{2-[2-(trifluoromethyl)-phenyl]ethynyl}-3,6,8-trioxabicyclo[3.3.0]oct-2-yl)purin-6-yl]cyclopentylamine, a compound of formula (6).
