As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 149765-15-1, name is N-(4-Chloro-7H-pyrrolo[2,3-d]pyrimidin-2-yl)-2,2-dimethylpropionamide, molecular formula is C11H13ClN4O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. COA of Formula: C11H13ClN4O
4-Chloro-5-iodo-2-trimethylacetamido-pyrrolor2.3-(flpyrimidine (9b).4-Chloro-2-trimethylacetamido-pyrrolo[2,3-rf]pyrimidine (9a, 10.9 g, 43.24 mmol) was dissolved in anhydrous THF (120 mL) under nitrogen. After the addition of LambdaModosuccinimide (10.7 g, 47.56 mmol), the mixture was stirred at RT for 1 h. The solvent was then removed in vacuo. The residue dissolved in EtOAc (100 mL) and washed with 1 M sodium thiosulfate (3×100 mL). Column chromatography purification (2% MeOH in DCM, isocratic ) yielded 9b (12.9 g). 1H-NMR (DMSO-rfbeta): 1.2 (9H, s), 7.8 (IH, d, Ji = 4 Hz), 10.1 (IH, s), 12.7 (IH, s).
With the rapid development of chemical substances, we look forward to future research findings about 149765-15-1.
