Procedure

A mixture of 210 mg (0.5 mmol) 2-chloro-N-{3-[4-((R)-1-phenyl-ethylamino)-7H-pyrrolo[2,3-d]pyrimidin-6-yl]-benzyl}-acetamide in 3 ml dry dioxane is treated with 268 μl (1.5 mmol) of a 5.6 N dimethylamine solution in ethanol (Fluka, Buchs, Switzerland) and then heated to 100° C. for 6 h. The clear yellow solution is cooled and the solvent evaporated. The residue is purified by flash chromatography using a mixture of dichloromethane/methanol with gradually increasing concentrations of methanol starting with 100:2.5 and ending with 100:5 and then switching to dichloromethane/methanol/conc. ammonia starting with 100:5:0.25 and ending with 100:10:0.5. The title compound is obtained as a colorless foam; Rf (dichloromethane/methanol/conc. ammonia 90:10:1)=0.41; MS-ES+: (M+H)+=429.
