실험 절차

To a solution of (1S,3R)-3-[(tert-butoxycarbonyl)amino]-1-isopropylcyclopentanecarboxylic acid (0.288 g, 1.06 mmol) and 4-(trifluoromethyl)-1′,2′,3′,6′-tetrahydro-2,4′-bipyridine dihydrochloride (0.320 g, 1.06 mmol) in dry methylene chloride (11.5 mL) was added triethylamine (0.592 mL, 4.25 mmol) followed by benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (0.517 g, 1.17 mmol). After being stirred at room temperature overnight, the brown reaction mixture was washed with NaHCO3 and brine, dried (MgSO4), filtered, and concentrated. The residue was purified by column chromatography on silica gel (30:70 EtOAc/hexanes) to provide a light yellow solid product: 265 mg (52%). LC-MS calculated for C25H34F3N3O3: (M+H) 482; found 382.2 (M-Boc+1).
