Reaction Steps

Using general method A, using THF instead of DMF as solvent, {3-[(5-chloro-thiophene-2-carbonyl)-amino]-[1,2,4]triazol-1-yl}-acetic acid (example 61.3) was reacted with 1-(N-methyl-4-piperidyl)-piperazine to give 5-chloro-thiophene-2-carboxylic acid (1-{2-[4-(1-methyl-piperidin-4-yl)-piperazin-1-yl]-2-oxo-ethyl}-1H-[1,2,4]triazol-3-yl)-amide. Off-white solid. MS 452.3 ([M+H]+)
