Adding a certain compound to certain chemical reactions, such as: 722-92-9, 2-(4-Aminophenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 722-92-9, blongs to alcohols-buliding-blocks compound. COA of Formula: C9H7F6NO
2-(tert-Butoxycarbonyl)-5-(methylsulfonyl)isoindoline- 1 -carboxylic acid (4.40 g, 12.89 mmol) and 2-(4-aminophenyl)- 1,1,1,3,3,3 -hexafluoropropan-2-ol (3.34 g, 12.89 mmol)were combined in EtOAc (50 mL) to give a suspension, before the addition of triethylamine (5.39 mL, 38.67 mmol) gave a dark brown solution. The solution was chilled by stirring on an ice I water bath before the addition of T3P (50percent in EtOAc, 15.35 mL, 25.78 mmol) through a dropping funnel. The addition was controlled to ensure that the temperature did not exceed 5 ¡ãC. After one hour the reaction solution was washed withwater (2 x 5OmL). The combined water washes were extracted with EtOAc (5OmL). The combined organic extracts were washed with 0. 1M aq HC1 (2 x 5OmL) and brine (25mL) before being dried over MgSO4. Filtration and concentration in vacuo gave a residue, which was purified by flash chromatography eluting with 0 ? 60percent EtOAc in n-heptane to give the title compound (4.95 g, 66percent) as a solid.LCIMS: mlzrr 581 EM-H]-. ?H NMR (400 MHz, DMSO-d6, mixture of rotamers, 1.8*:1) 151.35*, 1.47 (s, 9H), 3.20, 3.21* (s, 3H), 4.69? 4.88 (m, 2H), 5.61*, 5.63 (s, 1H), 7.6?7.76 (m, 5H), 7.86?7.92 (m, 1H), 7.98, 8.01* (s, 1H), 8.63*, 8.65 (s, 1H), 10.75 (s, 1H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,722-92-9, its application will become more common.
