Participants

Reaction Steps

A solution of 2-(3,5-bis-trifluoromethyl-phenyl)-2-methyl-propionyl chloride (the preparation of which is described in WO2002079134) (90 mg, 0.28 mmol) in CH2Cl2 (5 ml) was added drop wise to a stirred solution of rac-[(3S,4R)-1-benzyl-4-(4-fluoro-2-methyl-phenyl)-pyrrolidin-3-yl]-methyl-amine (77 mg, 0.26 mmol) and ethyl-diisopropyl-amine (0.07 ml, 0.38 mmol) in CH2Cl2 (5 ml). The reaction mixture was stirred 1 h, concentrated under vacuo and purification by flash chromatography (SiO2, EtOAc/H, 1:4) yielded 80 mg (54%) of the title product as colorless oil. ES-MS m/e: 581.2 (M+H+).
