1500-85-2, A common compound: 1500-85-2, name is 7H-Pyrrolo[2,3-d]pyrimidin-4-amine,molecular formula is C6H6N4, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
General procedure: Procedure G: To a solution of 7H-pyrrolo[2,3-d]pyrimidin-4-amine (1, 0.32 g, 2.39 mmol) and 2?-chloro-4?-methylspiro[cyclohexane-1,7?-pyrrolo[3,4-b]pyridin]-5?(6?H)-one (2, 0.6 g, 2.39 mmol) in 1,4-dioxane (15 mL) was added cesium carbonate (2.33 g, 7.17 mmol). The reaction mixture was purged with argon for 5 min. and then XanthPhos (69 mg, 0.11 mmol), XPhos (57 mg, 0.11 mmol), tris(dibenzylideneacetone)dipalladium(0) (109 mg, 0.11 mmol) and palladium acetate (27 mg, 0.11 mmol) were added and the reaction mixture purged for an additional 5 min. The purged reaction mixture was stirred at 100 C. for 4 h. After TLC showed completion, the reaction mixture was filtered through a bed of celite and the resulting filtrate was concentrated. The crude product was purified by preparative HPLC. The desired fractions were concentrated to dryness under vacuum to afford 2?-(4-amino-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-4?-methylspiro[cyclohexane-1,7?-pyrrolo[3,4-b]pyridin]-5?(6?H)-one as a yellow solid. Yield: 0.095 g, 11%;
With the rapid development of chemical substances, we look forward to future research findings about 1500-85-2.
