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. 3032-81-3, name is 1,3-Dichloro-5-iodobenzene, This compound has unique chemical properties. The synthetic route is as follows., 3032-81-3
To an oven dried 8 mL vial with teflon cap purged with N2 was added Zinc dust (298 mg, 4.56 mmol), DMF(1.5 mL), and iodine (57.8 mg, 0.228 mmol). To this mixture was added (R)-methyl 2-((tert-butoxycarbonyl)amino)-3-iodopropanoate (500 mg, 1.519 mmol), immediately followed by iodine (57.8 mg, 0.228 mmol).Pd2(dba)3 (69.6 mg, 0.076 mmol), 2-DICYCLOHEXYLPHOSPHINO-2?,6?-DIMETHOXYBIPHENYL(62.4 mg, 0.152 mmol), 1,3-dichloro-5-iodobenzene (622 mg, 2.279 mmol) and the reaction mixture wasallowed to stir at rt for 16 h. The crude mixture was diluted in EtOAc (30 mL) and DMF was removed withfour aqueous washes. The organic phase was dried over anhydrous sodium sulfate. The solution was filteredand concentrated, and the crude was purified by silica gel chromatography using 100percent hexanes to 30percentEtOAc/Hexanes. The desired product was obtained as a pale yellow oil, (S)-methyl 2-((tertbutoxycarbonyl)amino)-3-(3,5-dichlorophenyl)propanoate, 0.160 g yield in 77percent purity by LCMS analysis.Analysis LCMS condition F: Retention time=2.84 min; ESI-MS(+) m/z 348.1 (M+H).
