Related Products of 271-70-5, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 271-70-5, name is 7H-Pyrrolo[2,3-d]pyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
General procedure: Procedure A: To a solution of 5-bromo-2-(4-methoxybenzyl)isoindolin-1-one (1, 0.5 g, 1.5 mmol) in dioxane (10 mL) was added 7H-pyrrolo[2,3-d]pyrimidine (2, 0.27 g, 2.25 mmol) and potassium tert-butoxide (0.51 g, 4.52 mmol) followed by the addition of XantPhos (0.087 g, 0.15 mmol). The reaction mixture was degassed with argon for 15 min. Tris(dibenzylideneacetone)dipalladium(0) (0.14 g, 0.15 mmol) was then added and the reaction mixture was heated at 90 C. and maintained at that temperature for 12 h. (0193) Following heating, the reaction mixture was cooled and concentrated under reduced pressure. The concentrated reaction mixture was extracted in ethyl acetate. The organic layer was separated, dried over sodium sulphate, filtered and concentrated under reduced pressure. The residue obtained was purified by silica gel (100-200 mesh) column chromatography using 5% methanol in dichloromethane as eluent so as to afford 2-(4-methoxybenzyl)-5-(7H-pyrrolo[2,3-d]pyrimidin-7-yl)isoindolin-1-one (3). Yield: 0.21 g, 38%;
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 271-70-5, 7H-Pyrrolo[2,3-d]pyrimidine.
