An efficient synthesis of the angiotensin II inhibitor Valsartan (Diovan) is presented. The formation of the aryl–aryl bond represents the key step of its synthesis, which has been done by a Suzuki coupling of aryl boronate with 2-bromophenyl oxazoline with good yield and purity. This method overcomes many of the drawbacks associated with the previously reported syntheses.
