Conditions

Temperature: 70 °C

Procedure

Piperidine-4-carboxylic acid [4-phenyl-1-(3-phenyl-propyl)-butyl]-amide (4) (150.7 mg; 0.4 mmol) is dissolved in isopropanol (10 mL) at ambient temperature. (+/−)-2-(3,4,5-Trimethoxy-phenoxymethyl)-oxirane (95.2 mg; 0.4 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 (10%→100% acetone in hexanes) affording the desired product (145.9 mg) as an oil. ESMS:MH+ 619.4 (base).
