Procedure

A solution of (R)-2-Cyclohexylmethyl-4-morpholin-4-yl-4-oxo-butyric acid (223 mg, 0.788 mmol) in dimethylformamide (10 ml) was treated successively with (S)-2-Amino-1-(5-trifluoromethyl-1,2,4-oxadiazol-3-yl)-butan-1-ol; compound with trifluoroacetic acid (267 mg, 0.788 mmol), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (299 mg, 0.787 mmol) and diisopropylethylarmine (0.274 ml, 1.576 mmol). Reaction stirred at room temperature overnight. Solvent evaporated under reduced pressure. Residue taken up in ethyl acetate and washed with 1N hydrochloric acid, saturated aqueous bicarbonate solution and water, dried over Na2SO4 and solvent evaporated under reduced pressure to give (R)-2-Cyclohexylmethyl-N-{(S)-1-[hydroxy-(5-trifluoromethyl-1,2,4-oxadiazol-3-yl)-methyl]-propyl}-4-morpholin-4-yl-4-oxo-butyramide as a yellow solid (324 mg).
