実験手順

A mixture of (2R,5R)-5-chloromethyl-4-{2-[6-(2,4-difluoro-benzyl)-3,3-dimethyl-2,3-dihydro-pyrrolo[3,2-c]pyridin-1-yl]-2-oxo-ethyl}-2-methyl-piperazine-1-carboxylic acid tert-butyl ester (124 mg, 0.23 mmol), potassium iodide (83 mg, 0.5 mmol), anhydrous potassium carbonate (276 mg, 2.0 mmol) and 1H-pyrimidin-2-one (48 mg, 0.5 mmol) in acetonitrile (5 mL) was stirred and held at reflux in a sealed tube for 16 hours. Upon cooling to room temperature the solvent was removed in vacuo and the residues partitioned between DCM and water. The organic layer was separated, the solvent removed in vacuo and the residues were purified by column chromatography (silica, elution with 30-100% ethyl acetate in petroleum ether then 0-50% methanol in ethyl acetate) to give (2R,5S)-4-{2-[6-(2,4-difluoro-benzyl)-3,3-dimethyl-2,3-dihydro-pyrrolo[3,2-c]pyridin-1-yl]-2-oxo-ethyl}-2-methyl-5-(2-oxo-2H-pyrimidin-1-ylmethyl)-piperazine-1-carboxylic acid tert-butyl ester (70 mg, 49%) as a colourless solid. MS: [M+H]+=623. Compounds of Table 7 below were prepared using procedures analogous to that described in General Procedure 6 above, by reaction of the appropriate nucleophile with the appropriate substituted halopiperazine-amide (synthesised as described above, Preparation reference number given).
