4 Example 4Preparation of compound
2- iodoxybenzoic acid (3.83kg) was added to the reaction vessel was charged 16LDMF, stirring. Compound (2.4kg) was dissolved with 5LDMF dropwise added to the kettle, controlling the temperature of 20-30 deg.] C, the reaction is completed by stirring 1 ~ 2h, ethyl acetate was added 25L, stirring for 30min, the precipitated solid was filtered off. 80L of water was then added with stirring the organic phase was washed, the organic phase was separated, the aqueous phase was extracted once with ethyl acetate. The combined organic phase was washed with saturated sodium bicarbonate solution, dried and concentrated to give compound 1814g, yield 76.2%.
