実験手順

To a solution of dimethyl(2S,3S,5R)-5-hydroxy-2-[(4-phenylpiperazin-1-yl)carbonyl]piperidine-1,3-dicarboxylate (50.0 mg, 0.000123 mol) in tetrahydrofuran (0.50 mL, 0.00617 mol) was added 3-fluoro-phenol (0.0134 mL, 0.000148 mol), triphenylphosphine (38.8 mg, 0.000148 mol), followed by diethyl azodicarboxylate (0.0233 mL, 0.000148 mol). The mixture was heated at 70 Celsius overnight. After concentrated to dry, the mixture was purified on silica gel, eluting with 0 to 40% EtOAc in hexane, to generate the phenyl ether compound (27 mg, 44%). MS (ESI): (M+H)+=500.05.
