Dimethylformamide → HCID 14796402, compound

Participants

Reaction Steps

To a suspension of 9 g of 3-[4-(3-dimethylaminopropoxy)phenyl]-1H-pyrazolo[3,4-b]pyridine, 30 ml of dimethylformamide and 6.2 g of potassium carbonate was added dropwise 6.6 g of benzyl chloroacetate at 50° C. over the period of 2 hours. The mixture was kept at the same temperature for 4 hours. After the completion of the reaction, the reaction mixture was cooled. Water was added thereto, and the mixture was extracted with toluene. The extract was washed with water. After toluene was distilled off, diisopropyl ether was added to the residue for crystallization. The resulting crystals were recrystallized from diisopropyl ether - ethyl acetate to give benzyl 3-[4-(3-dimethylaminopropoxy)phenyl]-1H-pyrazolo[3,4-b]pyridin-1-ylacetate, m.p. 90°-92° C.
