Reference of 933702-55-7, 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 933702-55-7, name is 2-Chloropyrimidine-5-carbaldehyde. This compound has unique chemical properties. The synthetic route is as follows.
2401-2403, in 16 ml of tetrahydrofuran was cooled to 0 C. and 1.6 ml (2.6 mmol) of 1.7 N n-butyl lithium/n-hexane solution was added thereto, and the reaction solution was stirred at room temperature for 30 minutes. The reaction solution was cooled to 0 C. again and then a solution of 0.31 g (2.2 mmol) of 2-chloropyrimidin-5-carbaldehyde in 4 ml of tetrahydrofuran was added to the reaction solution, and the reaction solution was stirred at room temperature for 30 minutes. After completion of the reaction, saturated ammonium chloride aqueous solution was added to the reaction solution and the reaction solution was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride aqueous solution and dried with anhydrous sodium sulfate, and then the solvent was distilled off under reduced pressure. The obtained residue was subjected to silica gel column chromatography [n-hexane/ethyl acetate=100/0-80/20 (V/V)] and the fraction including the desired compound was concentrated under reduced pressure to provide 0.17 g of 2-chloro-5-(4,4,4-trifluoro-1-buten-1-yl)pyrimidine.
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 933702-55-7, 2-Chloropyrimidine-5-carbaldehyde.
