102351 A reactor was charged with toluene (24 Kg), and stirring was initiated. The reactor was then charged with 5-phenoxyphthalide (56 Kg), thionyl chloride (41 Kg), trimethyl borate (1 Kg), dichlorotriphenylphosphorane (2.5 Kg), and potassium carbonate (77 Kg). The mixture was heated to reflux until reaction completion and solvent was removed leaving 2-chloromethyl-4-phenoxybenzoylchloride. Methanol was charged and the mixture was heated above 50 C until reaction completion. Solvent was removed and replaced with DMF. This solution of the product methyl 2-chloromethyl-4- phenoxybenzoic acid methyl ester in DMF was used directly in the next step (HPLC: 85%).
57830-14-5 5-Phenoxyisobenzofuran-1(3H)-one 44558580, abenzofuran compound, is more and more widely used in various fields.
