Application of 56096-89-0,Some common heterocyclic compound, 56096-89-0, name is 4-Fluoro-2-iodobenzoic acid, molecular formula is C7H4FIO2, 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.
A mixture of a (1 33 g, 5 mmol, 1.0 eq), b (1.5 g, 7 5 mmol, 1.5 eq), KOAc (1.3 g, 12.5 mmol, 2.5 eq), copper powder (100.0 mg, 1.5 mmol, 0.3 eq), and Cui OAc)?. (270.0 mg, 1.5 mmol, 0.3 eq) in 2-pentanol (30.0 mL) was stirred at 140 C overnight under N2 atmosphere, then cooled to room temperature. The mixture was diluted with water (100 mL), acidified to pH=3 with 2 N HC1 and extracted with EtOAc (100 mL x 2). The combined organic layers were dried over anhydrous NaiSCL and concentrated. The residue was purified by chromatography on silica gel (EtOAc) to afford c (1.14 g, 66%). LC/MS: 341.9
The synthetic route of 56096-89-0 has been constantly updated, and we look forward to future research findings.
