実験手順

To a solution of 100 mg (0.32 mmoles) of 6-bromomethyl-7-(2,2-dimethyl-propyl)-7H-pyrrolo[2,3-d]pyrimidine-2-carbonitrile and 150 mg (0.96 mmoles) of piperidin-4-one in 5 ml of DMF, 88 mg (0.64 mmoles) of K2CO3 is added at ambient temperature. After being stirred for 18 hours, the reaction mixture is quenched with H2O and the mixture is extracted with AcOEt. The combined extracts are washed with brine, dried over MgSO4 and concentrated under reduced pressure. The residue is purified by silica gel column chromatography to give 96 mg of disired 7-(2,2-dimethyl-propyl)-6-(4-oxo-piperidin-1-ylmethyl)-7H-pyrrolo[2,3-d]pyrimidine-2-carbonitrile in 92% yield.
