Versuchsvorschrift
To 1,1-dimethylethyl 4-[2-(5-bromo-4-chloro-7H-pyrrolo[2,3-d]pyrimidin-7-yl)ethyl]-1-piperidinecarboxylate (320 mg, 0.721 mmol) in a 5 ml sealable vial was added ammonium hydroxide (1.5 mL, 38.5 mmol). The vial was then capped and heated at 90° C. overnight. The reaction was then cooled and the solid was isolated filtration and washed with NH4OH. The solid was then air dried to give 1,1-dimethylethyl 4-[2-(4-amino-5-bromo-7H-pyrrolo[2,3-d]pyrimidin-7-yl)ethyl]-1-piperidinecarboxylate (309 mg) as an off white solid that contained a small amount of starting material. It was used without further purification. LC-MS (ES) m/z=424.4 [M+H]+.
