3,4-Dinitrophenol → 4-(3,4-dinitro-phenoxy)-7,7a-dihydro-4aH-pyrrolo[2,3-d]pyrimidine

Participants

Reaction Steps

4-Chloro-7,7a-dihydro-4aH-pyrrolo[2,3-d]pyrimidine (1.66 g, 10.8 mmol), 3,4-dinitrophenol (2.4 g, 13 mmol) and TFA/TEA were heated at 150° C. for 2 h. The resulting green solid was purified on silica gel using a Hexane/EtOAc gradient (100/0 to 50/50) to give 4-(3,4-dinitro-phenoxy)-7,7a-dihydro-4aH-pyrrolo[2,3-d]pyrimidine.
