24621-61-2,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 downstream synthesis route of the compound 24621-61-2
To a stirring solution of (S)-1, 3-butanediol (1.0 g, 0.01 MMOL) and triethylamine (1.39 g, 0.014 MMOL) in dichloromethane (10 mL) at-20C was added dropwise p- toluenesulfonyl chloride and the mixture was stirred for 2 h. The reaction mixture was then warmed to RT and stirred overnight. The reaction mixture was poured into cold H20 (20 mL), and extracted three times with DICHLOROMETHANE. The organic extracts were then washed with brine. The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo to give 2.6 g (96% yield) of title compound as an oil. MS (ESI) 244.8 (M+). The crude tosylat was used without further purification., 24621-61-2
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 24621-61-2.
