Procedure
1.1 A suspension of 1.00 g (6.32 mmol) of 4-chloro-7H-pyrrolo[2,3-d]-pyrimidine and 5.20 g (15.8 mmol) of caesium carbonate in 30 ml of 2-methoxy-ethanol is heated under reflux for 24 hours. The reaction mixture is adsorbed onto kieselguhr and chromatographed on a silica-gel column with dichloromethane/methanol/aqueous ammonia (100:1:1) as eluent, giving 4-(2-methoxyethoxy)-7H-pyrrolo[2,3-d]pyrimidine as colourless crystals; m.p. 137-139° C.;
