Reaction Steps

In analogy to example 47.3, 2-(2-amino-thiazol-4-yl)-1-[4-(1-methyl-piperidin-4-yl)-piperazin-1-yl]-ethanone trihydrobromide (example 47.2) was coupled with 5-chlorthiophene-2-carboxylic acid, using general method D, to give 5-chloro-thiophene-2-carboxylic acid (4-{2-[4-(1-methyl-piperidin-4-yl)-piperazin-1-yl]-2-oxo-ethyl}-thiazol-2-yl)-amide. Light orange solid. MS 468.5 ([M+H]+)
