실험 절차

To a mixture of (S)-4,4-difluoro-2-[(morpholine-4-carbonyl)-amino]-heptanoic acid (104 mg, 0.35 mmol), (S)-2-amino-1-(3-cyclopropyl-1,2,4-oxadiazol-5-yl)-butan-1-ol hydrochloride (86.7 mg, 0.37 mmol) and diisopropyl amine (219 mg, 0.42 mmol) in dry dichloromethane (5 mL) is added PyBOP (113 mg, 0.87 mmol). The mixture is stirred at room temperature for 16 hr and the evaporated in vacuum. The residue is diluted with ethyl acetate (25 mL) and washed with saturated NaHCO3 (30 mL), dilute HCl (30 mL), then saturated NaHCO3 (30 mL). The organic layer is dried over magnesium sulfate and concentrated in vacuum. The residue is purified over 12 g silica gel, eluting with ethyl acetate: heptane (2:1 then 1:0) to afford morpholine-4-carboxylic acid (1-{1-[(3-cyclopropyl-[1,2,4]oxadiazol-5-yl)-hydroxy-methyl]-propylcarbamoyl}-3,3-difluoro-hexyl)-amide (146 mg, 88%) as a solid. LC/MS shows 2 isomers, total 100% M+1 474.
