We describe an efficient protocol for the Suzuki–Miyaura synthesis of ortho-substituted biphenyl oxazolines from 2-(2-bromophenyl)-4,4-dimethyl-2-oxazoline and aryl boronic acids or aryl boronates. The Suzuki coupling is carried out in the presence of Pd(PPh3)4 and sodium carbonate in aqueous tetrahydrofuran. The scope and limitations of the reaction are discussed.
