Versuchsvorschrift

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 230 mg (0.96 mmoles) of piperidine-4-carboxylic acid phenylamide in 5 ml of DMF, 130 mg (0.96 mmoles) of K2CO3 is added at ambient temperature. The reaction mixture is stirred for 18 hours at ambient temperature. The reaction mixture is quenched with H2O and 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 130 mg of disired 1-[2-cyano-7-(2,2-dimethyl-propyl)-7H-pyrrolo[2,3-d]pyrimidin-6-ylmethyl]-piperidine-4-carboxylic acid phenylamide in 95% yield.
