Herein, we report a nickel-catalyzed crossing-coupling reaction for the synthesis of diaryl ethers. The desired products are achieved by coupling heterocyclic alcohols with aryl bromides bearing strong electron withdrawing nitro group under the catalyst system of NiCl2(PPh3)2 and weak base KHCO3. This mild reaction exhibits a broad functional group tolerance. Compound 4 as an important intermediate is suitable for further structural modification of MALT1 inhibitor MI-2.
