Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 137281-39-1, name is 4-(2-(2-Amino-4-oxo-4,7-dihydro-1H-pyrrolo[2,3-d]pyrimidin-5-yl)ethyl)benzoic acid. A new synthetic method of this compound is introduced below., Recommanded Product: 4-(2-(2-Amino-4-oxo-4,7-dihydro-1H-pyrrolo[2,3-d]pyrimidin-5-yl)ethyl)benzoic acid
General procedure: To a suspension of compound 6 (0.033 mmol) in N,N-dimethylformamide (5 mL), corresponding amine (RNH2) (0.033 mmol) and DIPEA (0.1 mmol) were added at about 10 C under nitrogen atmosphere. To this, diethylphosphorocyanidate(0.04 mmol) was added slowly over a period of 15 min. The resultant solution was stirred for 3 h at about 10 C. The reaction was complete by TLC (TLC system: 10% methanol in chloroform). Reaction was slowly quenched using saturated sodium-bi-carbonate solution and the resulted solid was stirred for 30min. Solid was collected by filtration and the wet cake was washed with saturated sodium-bi-carbonate solution. Upon drying the wet cake for an hour under vacuum, it was further suspended in methanol and stirred for 30 min, filtered, collected and dried to get respective pure compounds.
