Versuchsvorschrift

0.5 g (3 mmol) of 4-chloro-2-methyl-7H-pyrrolo[2,3-d]pyrimidine (prepared according to West and Beauchamp, J. Org. Chem. 26 (1961) 3809) was dissolved in 3 ml DMF and 2.06 g (15 mmol) of potassium carbonate was added to this solution. 0.431 ml (3 mmol) of 4-bromobutyric acid ethyl ester was added and the mixture was stirred at 50° C. for 45 minutes. The reaction mixture was diluted with 50 ml EE and washed three times with water, dried over MgSO4, filtered and the solvent was removed in vacuo. Yield: 0.8 g.
