Application of 13421-13-1, A common heterocyclic compound, 13421-13-1, name is 4-Chloro-2-iodobenzoic acid, molecular formula is C7H4ClIO2, its 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.
Example 3Amethyl 4-chloro-2-iodobenzoate To a solution of 4-chIoro-2-iodobenzoic acid (10.61 g, 37.62 mmol) in methanol (75 ml), trimethylsilyldiazomethane (30 ml, 2.0 M in ether) was added drop by drop. 1725 After 1 hour, another batch of trimethylsilyldiazomethane (26 ml, 2.0 M in ether) was added drop by drop. The reaction mixture was stirred at room temperature overnight and concentrated. The crude product was purified by column chromatography (0-20% ethyl acetate in hexanes) to yield the title compound.
The synthetic route of 13421-13-1 has been constantly updated, and we look forward to future research findings.
