Reaction Conditions:
with 5%-palladium/activated carbon;hydrogen in ethanol; under 15001.5 Torr; for 8 h;
Steps:
4 Example 4
Weighing intermediate 1,3-bis(3-nitrophenoxy)benzene 106g,5% palladium on carbon 1.4g (50% water),750g of ethanol was added to the 2L hydrogenation kettle.After replacing the nitrogen three times, the hydrogen was replaced three times.Pressurize to 2MPa for 8h,After the reaction,Filter to remove Pd carbon,The filtrate is concentrated and desolved to remove 80% ethanol.Cool down to 20 ° C and stir and crystallize for 30 minutes.Filtering,Rinse with cold water 2-3 times,Drying at 60 ° C under vacuum gave 82.7 g of the desired product 1,3-bis(3-aminophenoxy)benzene as a white crystal.Yield 94%,HPLC = 99.2%.
