Reaction Steps

In analogy to example 24B 5-chloro-thiophene-2-carboxylic acid {(1S,4R)-4-[2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenylcarbamoyl]-2-oxo-cyclopentyl}-amide was reacted with methylamine (using a saturated solution in THF) to give 5-chloro-thiophene-2-carboxylic acid {(S)-4-[2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenylcarbamoyl]-2-methylamino-cyclopentyl}-amide. Crystalline white solid. MS 489.3 ([M+H]+).
