Related Products of 90213-67-5, 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 90213-67-5, name is 2,4-Dichloro-7-methyl-7H-pyrrolo[2,3-d]pyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
General procedure: Sonogashira Coupling; Compound 2a: A solution of 1(400 mg, 1.98 mmol) in anhyd Et3N (20 mL) was flushed withargon and Pd(PPh3)2Cl2 (28.0 mg, 0.04 mmol), PPh3 (21.0 mg,0.08 mmol), CuI (3.8 mg, 0.02 mmol) and phenylacetylene (260muL, 2.38 mmol) were added. The mixture was stirred underargon at 60 C for 2-3 h. After cooling, the reaction mixture waspoured into H2O (40 mL) and extracted with CHCl3. The extractwas dried over Na2SO4, filtered and the solvent removed byrotary evaporation. The residue was purified by column chromatography(eluent CHCl3) and recrystallized to give compound 2a.
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 90213-67-5, 2,4-Dichloro-7-methyl-7H-pyrrolo[2,3-d]pyrimidine.
