Dimethylformamide → HCID 86626256, compound

Participants

Reaction Steps

A mixture of 4-chloro-5H-pyrrolo[3,2-d]pyrimidine (1.51 g), tert-butyl (4-chlorobut-2-yn-1-yl)carbamate (2.60 g), cesium carbonate (4.80 g) and N,N-dimethylformamide (15 mL) was stirred at room temperature for 2 hrs. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was separated and purified by silica gel column chromatography (eluent, hexane:ethyl acetate=80:20→33:67) to give the title compound (2.61 g) as an orange oil.
