Reaction Steps

To a solution of (1S,3R)-3-[(tert-butoxycarbonyl)amino]-1-isopropylcyclopentanecarboxylic acid (115 mg, 0.424 mmol) and 4-[2-(trifluoromethyl)phenyl]-1,2,3,6-tetrahydropyridine trifluoroacetate (152 mg, 0.445 mmol) in methylene chloride (2 mL) was added triethylamine (0.21 g, 2.1 mmol) followed by benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (210 mg, 0.47 mmol). After being stirred overnight at room temperature, the reaction was quenched with saturated NaHCO3 solution. The resulting solution was extracted with methylene chloride three times. The combined extracts were dried (MgSO4), filtered, and concentrated. Purification by flash chromatography on silica gel (0-50% B over 15 min. Bottle A=hexanes, Bottle B=EtOAc) provided 174 mg of desired product as a white solid. MS calculated for C26H35F3N2O3: (M+H) 481; found 481.1.
