Quinoline-6-carboxylic acid (1-benzyl-2-hydroxy-3-{3-[-phenyl-1-(3-phenyl-propyl)-butylcarbamoyl]-piperidin-1-yl}-propyl)-amide

Procedure

1-(3-Amino-2-hydroxy-4-phenyl-butyl)-piperidine-3-carboxylic acid [4-phenyl-1-(3-phenyl-propyl)-butyl]-amide (20) (150 mg; 0.28 mmol) is dissolved in methylene chloride (10 mL) at ambient temperature. 6-Quinolinecarboxylic acid (48 mg; 0.28 mmol), triethylamine (0.0772 mL; 0.55 mmol), and N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (58.4 mg; 0.31 mmol) are added sequentially. The mixture is stirred for 18 hours at ambient temperature then concentrated in vacuo at 30° C. The residue is diluted with ethyl acetate (100 mL) and washed successively with water (50 mL), saturated aqueous sodium bicarbonate (50 mL), and saturated brine (50 mL). The organic layer is dried over MgSO4, filtered, and concentrated in vacuo. The residue is purified via silica gel chromatography with gradient elution (2%→20% methanol in methylene chloride) affording the desired product diastereomers (70 mg) as an oil. ESMS:MH+ 697.6 (base).
