実験手順

To a solution of 2(R)-[2,2,2-trifluoro-1-(S)-(4-fluorophenyl)ethylamino]-3-tritylsulfanylpropionic acid (21.58 g, 40 mmol; Reference D) and 1-aminocyclopropane-carbonitrile hydrochloride (OmegaChem, 6.16 g, 52 mmol) in DMF (75 mL) at rt was added DIPEA (Aldrich, 21 mL, 120 mmol) followed by solid HATU (ChemPacific, 19.77 g, 52 mmol) in one portion. This dark, homogeneous solution was allowed to stir at rt for 24 h. The reaction mixture was quenched by addition of 10% NaHCO3 (50 mL), followed by water (100 mL) and then extracted with EtOAc and the combined organics were washed with brine. Following drying over anhydrous MgSO4 and concentration in vacuo, the resulting dark oil was chromatographed on silica gel with 3/1 hex/EtOAc elution to afford a diastereomer mixture (ranging from 5.7/1 to 12/1) of N-(1-cyanocyclopropyl)-2-(R)-[2,2,2-trifluoro-1(S)-(4-fluorophenyl)ethylamino]-3-tritylsulfanylpropionamide and (9.83 g) as a yellow solid.
