実験手順

To 1,1-dimethylethyl (2S)-4-({6-[[(6-chloro-3-pyridinyl)carbonyl](methyl)amino]-3-pyridinyl}methyl)-2-methyl-1-piperazinecarboxylate (D106) (0.139 g, 0.303 mmol) in DMF (4 mL) under an argon atmosphere was added potassium carbonate (0.293 g, 0.212 mmol) and 4-fluorophenol (0.169 g, 1.51 mmol). The reaction mixture was stirred and heated at 130° C. for 5 h then concentrated in vacuo. The residue was re-dissolved in DCM/water. The organic layer was washed with 2M NaOH solution and brine then dried (Na2SO4) and concentrated to give the crude product which was purified by column chromatography. Elution with EtOAc/DCM gave the title compound as a colourless oil (0.054 g). MS (ES): MH+ 536.2.
