To a solution of 8-[2-cyano-7-(2-cyclohexyl-ethyl)-7H-pyrrolo[2,3-d]pyrimidin-6-ylmethyl]-2,8-diaza-spiro[4.5]decane-2-carboxylic acid tert-butyl ester (300 mg, 0.59 mmol) in dichloromethane (5 ml), trifluoroacetic acid (3 ml) is added. After stirring for 1.5 h at room temperature, solvent is evaporated down to give 7-(2-cyclohexyl-ethyl)-6-(2,8-diaza-spiro[4.5]dec-8-ylmethyl)-7H-pyrrolo[2,3-d]pyrimidine-2-carbonitrile trifluoroacetic acid salt in quant yield.
