Reaction Steps

Methylpiperazine (10 ul, 116 umol; CAS Reg. No. 109-01-3) and DIEA (20 ul, 93 umol) were added to a solution of (2S,4R)-1-(2-cyclobutyl-5-methyl-2H-pyrazol-3-yl)-4-(4-fluoro-2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid (1-cyano-cyclopropyl)-amide (25 mg, 46 umol; example 388 g) in acetonitrile (400 ul) under an argon atmosphere. The reaction mixture was stirred at ambient temperature for 72 h, the solvent was removed under reduced pressure and the residue was purified by preparative HPLC to give the title compound (14 mg, 23 umol; 49%) as colorless oil. MS (ESI): m/z=618.2 [M−H]−.
