Versuchsvorschrift
To 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (1, 3.5 g, 23.0 mmol) in 70 mL of methanol, potassium hydroxide (2.3 g, 41.0 mmol) is added and the reaction stirred at 60° C. overnight, then poured into water and extracted with ethyl acetate. The organic layer is separated and dried over sodium sulfate, filtered and the filtrate concentrated under vacuum to provide the desired compound (2, 3.20 g).
