INTERMEDIATE COMPOUNDS FOR THE PREPARATION OF AN ANGIOTENSIN II RECEPTOR ANTAGONIST

It comprises new substituted 4-valinylmethylphenyl boronic acids and their derivatives and also its preparation process. It also comprises a preparation process of Valsartan from such intermediates. The process comprises the reaction of the new 4-valinylmethylphenyl boronic compounds with a (halophenyl)tetrazole compound which proceeds with high yields. The process is particularly advantageous in its practical industrial realization because it avoids the use of azide derivatives and also the use of expensive biphenyl intermediates.
