15.15.2 15.2 Preparation of UV-326
In a 250mL three-necked flask, add 0.2g of the prepared 1% Pd/MgO catalyst,10g UV-326 azo intermediate, about 60mL toluene, 10g ammonia borane,Start stirring after heating to 50°C (stirring rate is about 600rpm), and react for 5h;After the reaction, the catalyst is filtered and the organic layer is separated,The composition of hydrogenation products in the filtrate was analyzed by high performance liquid chromatography; the solvent was evaporated under reduced pressure,After washing with deionized water and methanol, and drying, the target product is obtained.
