Product 1

HCID 46946414(2S,4R)-1-(2,2,3,3,3-pentafluoro-propyl)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid (1-cyano-cyclopropyl)-amide

Procedure

(2S,4R)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid (1-cyano-cyclopropyl)-amide hydrochloride from experiment K5 was reductively aminated with 2,2,3,3,3-pentafluoropropyltrifluoromethane sulfonate in analogy to experiment L3 to give (2S,4R)-1-(2,2,3,3,3-pentafluoro-propyl)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid (1-cyano-cyclopropyl)-amide as a pale brown oil. MS: 520.1 [M+H]+.
