Adding a certain compound to certain chemical reactions, such as: 431-38-9, 3-Amino-1,1,1-trifluoropropan-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, category: alcohols-buliding-blocks, blongs to alcohols-buliding-blocks compound. category: alcohols-buliding-blocks
Preparation 10: 4-(5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)-N-(3,3,3-trifluoro-2-hydroxypropyl)-1-naphthamide To a solution of 4-(5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)-1-naphthoic acid (Preparation 7, 1 g, 2.1 mmol) in DMF (25 mL) was added HATU (970 mg, 2.5 mmol) and triethylamine (1.0 mL, 7.0 mmol).The reaction was stirred at room temperature for 15 minutes then treated with 3-amino-1,1,1-trifluoro-2-propanol (275 mg, 2.1 mmol). The reaction was stirred at room temperature for 18 hours. Next, the reaction was diluted with 0.1NNaOH and extracted with EtOAc (2¡Á150 mL). The combined organic phase was dried (Na2SO4) and concentrated under vacuum. The crude material was chromatographed (80 g Redi-Sep column) eluting from 100% heptane to 40:60 EtOAc:heptane to afford the intermediate (1.06 g, 85%) as a solid. 1HNMR (CDCl3) delta ppm: 8.81 (1H), 8.28 (1H), 7.71-7.57 (5H), 7.49 (1H), 6.55 (1H) 4.32-4.25 (3H), 4.08-3.91 (1H), 3.85 (1H), 3.79-3.74 (1H); m/z (Cl) 583 [M+H]+.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,431-38-9, 3-Amino-1,1,1-trifluoropropan-2-ol, and friends who are interested can also refer to it.
