Reaction Steps

(2S,4R)-4-(2-Chlorophenylsulfonyl)-1-(3-methyl-1-(2-morpholinoethyl)-1H-pyrazol-5-yl)pyrrolidine-2-carboxylic acid methyl ester. In analogy to the procedure described in example 192 h, (2S,4R)-methyl 4-(2-chlorophenylsulfonyl)-1-(3-oxobutanethioyl)pyrrolidine-2-carboxylate (example 253c) was reacted with 4-(2-hydrazinoethyl)morpholine (CAS Reg. No. 2154-24-7) to give the title compound as yellow oil. MS (ESI): m/z=497.3 [M+H]+.
