Electric Literature of 13421-13-1, These common heterocyclic compound, 13421-13-1, name is 4-Chloro-2-iodobenzoic acid, 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.
