1,3-Bis(4-aminophenoxy)benzene Use and Manufacturing

Methods of Manufacturing

General procedure: The mixture of compound 1b, 2b or 3b (1.8g, 5.1mmol) and Pd/C (10percent, 0.2g) was stirred in methanol (70mL) for overnight under an hydrogen atmosphere at room temperature. After completion of present reaction, the mixture was processed by suction filtration, and then added 50mL water to the resulting filtrate, extracted with dichloromethane three times (3×50mL). The combined organic layers were washed with brine, dried (Na
