Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 132898-96-5, name is 2,3-Dioxoindoline-5-sulfonyl chloride, This compound has unique chemical properties. The synthetic route is as follows., Formula: C8H4ClNO4S
To a slurry of 2,3-dioxomdoline-5-sulfonyl chloride (Lee, D. et al. J. Med. Chem. 2001, 44, 2015) (7,07 g, 28.8 mmol) m CH2Cl2 (288 mL) at rt was added neopentyl alcohol (7.61 g, 86.3 mmol) then pyridine (11.6 mL, 143 mmol). The reaction was stirred at rt for 22 hours, becoming a clear, oiange solution. The reaction was diluted with ILO (300 mL) and extracted with EtOAc (2 chi 600 mL). The combined organic extracts were washed with 0.1 M aqueous HCl (3 * 300 mL), saturated aqueous NaHCO3 (300 mL), and saturated aqueous NaCl (300 mL), then dried over Na2SO4, filtered, and concentrated in vacuo to provide the title compound as a yellow solid (6.40 g, 92%). 1H NMR (400 MHz, CDClj): consistent; MS (ES ) m’z 315.1 (,VHH2O)
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 132898-96-5.
