実験手順

A suspension of (S)-4-methyl-2-(tetrahydro-pyran-4-ylamino)-pentanoic acid (430 mg, 2.00 mmol), N-methylmorpholine (0.220 mL, 2.00 mmol), and 4,4-bis-(4-fluoro-phenyl)-butylamine monohydrochloride (597 mg, 2.00 mmol) in dry DMF (10 mL) was treated with Triton® B (1.82 mL, 4.00 mmol, 40 weight percent solution in methanol, Aldrich, Milwaukee, Wis.), a clear solution was obtained and cooled to 0° C. in an ice-water bath. Solid O-benzotriazol-1-yl-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.760 g, 2.00 mmol) was then added. After stirring at 0° C. for 30 minutes, was added, the cooling bath was then removed, and the stirring was continued at ambient temperature for 30 minutes. After this period, the reaction mixture was mixed with 50 mL of diethyl ether; the resulting mixture was successively washed with saturated aqueous NaHCO3 solution (50 mL), brine (2×50 mL), and was dried over Na2SO4. The solution was concentrated in vacuo affording a viscous oil. The crude product was purified by flash chromatography (EtOAc:hexanes:MeOH 50:50:5) to give 300 mg (39%) of the pure titled compound as a clear oil. APCI-MS m/z 459.4 (MH+).
