Reaction Steps

In analogy to example 21C, (1SR,3RS,4SR)-3-{[(5-chloro-thiophene-2-carbonyl)-amino]-methyl}-4-hydroxy-cyclopentanecarboxylic acid methyl ester was reacted with 4-(4-amino-3-fluoro-phenyl)-morpholin-3-one (CAS 438056-69-0) to give 5-chloro-thiophene-2-carboxylic acid {(1RS,2SR,4SR)-4-[2-fluoro-4-(3-oxo-morpholin-4-yl)-phenylcarbamoyl]-2-hydroxy-cyclopentylmethyl}-amide. Orange solid. MS: 496.3. ([M+H]+).
