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. 271-70-5, name is 7H-Pyrrolo[2,3-d]pyrimidine, molecular formula is C6H5N3, 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. SDS of cas: 271-70-5
General procedure: Procedure C: A solution of 4-methyl-7H-pyrrolo[2,3-d]pyrimidine (1, 0.4 g, 3.0 mmol), 5-bromo-2-(4-methoxybenzyl) isoindolin-1-one (2, 1.0 g, 4.5 mmol) and potassium phosphate (1.91 g, 9.0 mmol) in 1, 4-dioxane (15 ml) was degassed with nitrogen for 10 min. Copper (I) iodide (0.28 g, 1.5 mmol) and trans-1, 2-diaminocyclohexane (0.17 g, 1.5 mmol) were added and the reaction was refluxed at 90 C. for 16 h. Progress of the reaction was monitored by TLC. After completion, solvent was removed under reduced pressure. The reaction mixture was diluted with water and extracted twice with ethyl acetate. The organic layer was separated, dried over sodium sulphate, filtered and concentrated under reduced pressure to afford 2-(4-methoxybenzyl)-5-(4-methyl-7H-pyrrolo [2, 3-d] pyrimidin-7-yl) isoindolin-1-one (3) as a yellow solid. Yield: 0.55 g, 47%;
With the rapid development of chemical substances, we look forward to future research findings about 271-70-5.
