Synthetic Route of 216393-67-8,Some common heterocyclic compound, 216393-67-8, name is 4-Chloro-2-fluoro-6-iodoaniline, molecular formula is C6H4ClFIN, 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.
INTERMEDIATE 65 – PREPARATION of A/-(2-(5-Chloro-7-fluoro-2-(triethylsilyl)-1H-indol-3- yl)ethyl)-4-(3-fluorobenzyl)benzamide. 4-Chloro-2-fluoro-6-iodoaniline (0.100 g; 0.368 mmol), 4-(3-fluorobenzyl)-N-(4- (triethylsilyl)but-3-ynyl)benzamide (0.145 g; 0.368 mmol), bis(diphenylphosphino)ferrocene]palladium(ll) chloride (0.015 g; 0.018 mmol), lithium chloride (0.016 mg; 0.368 mmol) and sodium carbonate (0.078 g; 0.737 mmol) were suspended in DMF (5 ml_) and the mixture was stirred at 100C for 18 hours. The solution was concentrated under reduced pressure and diluted in ethyl acetate. The organic layer was successively washed with brine, sodium thiosulfate, dried and concentrated under reduced pressure. The crude residue was purified by flash chromatography on silica gel (eluent 2 to 60 % ethyl acetate in heptane) to afford 0.102 g (51 %) of the title compound as a yellow oil. ESI/APCI(+): 539(M+H).
The synthetic route of 216393-67-8 has been constantly updated, and we look forward to future research findings.
