Product Information

• Name: N-(1-Oxobutyl)-N-[[2'-(2H-tetrazol-5-yl)[1,1'-biphenyl]-4-yl]methyl]-L-valine
• Synonyms: Valsartan n-propyl impurity
• Brand: Biosynth
• Description: N-(1-Oxobutyl)-N-[[2'-(2H-tetrazol-5-yl)[1,1'-biphenyl]-4-yl]methyl]-L-valine (GW1929) is a potent vasodilator that is used for the treatment of hypertension. It is synthesized by condensation of sodium hydroxide with 2-(4′-chlorophenyl)piperazine followed by methyl esterification and chloride acylation. The synthesis of GW1929 has been accomplished in two steps: carbonate cyclization and valsartan hydrolysis. In the first step, the carboxylic acid group of GW1929 was converted to its corresponding chloride compound which was then reacted with methyl bromide to yield the desired product. The second step involved hydrolysis of GW1929 with potassium carbonate, after which it was oxidized with azide to form an ester. Sodium
