Conditions

Temperature: 70 °C

Procedure

Methylpiperidine-4-carboxylic acid [4-phenyl-1-(3-phenyl-propyl)-butyl]-amide (57) (150 mg; 0.382 mmol) is dissolved in isopropanol (10 mL) at ambient temperature. (R)-5-Oxiranylmethoxy-quinoline (2) (77.5 mg; 0.382 mmol) is added, then the mixture is heated to 70° C. and maintained for 18 hours. After cooling to ambient temperature, the solution is concentrated in vacuo at 40° C. The residue is purified via silica gel chromatography with gradient elution (0%→25% methanol in methylene chloride) affording the desired product (187.4 mg) as a solid foam. ESMS: MH+ 594.4 (base).
