Procedure

Lithium (R)-1-[2-hydroxy-3-(quinolin-5-yloxy)-propyl]-piperidine-4-carboxylate (32) (100 mg; 0.297 mmol) is dissolved in methylene chloride (3 mL) at ambient temperature. Dibenzylamine (41) (62 mg; 0.312 mmol), N,N-diisopropylethylamine (85 mg; 0.654 mmol) and PyBOP (186 mg; 0.357 mmol) are added sequentially. The reaction is stirred for 18 hr. at room temperature, then concentrated under reduced pressure. The residue is purified via silica gel chromatography with gradient elution (90% ethyl acetate in hexanes, then 50%→100% acetone in hexanes) affording the desired product (42) as a solid. CIMS (NH3Cl): 510 (MH+)
