Procedure

To sodium hydride (0.0174 g, 60% dispersion in mineral oil, 0.436 mmol) in DMF (4 mL) was added 4-fluorophenol (0.0488 g, 0.436 mmol) and the mixture stirred under an argon atmosphere for 20 minutes. 1,1-Dimethylethyl (2S)-4-({4-[[(6-chloro-2-pyridinyl)carbonyl](methyl)amino]phenyl}methyl)-2-methyl-1-piperazinecarboxylate (D107) (0.100 g, 0.218 mmol) was added and the reaction mixture was heated in a microwave at 190° C. for 1.5 h. The reaction mixture was concentrated and the residue partitioned between DCM and water. The aqueous layer was further extracted with DCM and the combined organics were dried over Na2SO4 and concentrated to give a yellow oil which was purified by column chromatography to give the title compound as a colourless oil (0.0539 g). MS (ES): MH+ 535.4.
