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, 431-38-9, blongs to alcohols-buliding-blocks compound. 431-38-9
A solution of 100 mg intermediate 32, 75 mg 3-amino-1 ,1 ,1 -trifluoropropan-2-ol, 167 mg HATU and 0.15 mL ethyldiisopropylamine in 5 mL of DMF was stirred at room temperature for 14 hours. Then the reaction was quenched by water, and the mixture was extracted with dichloromethane two times. The combined organic phases were dried over sodium sulfate and evaporated to dryness. The residue was subjected to RP-HPLC (column: X-Bridge C18 5muetaiota 100x30mm, mobile phase: acetonitrile / water (0.1 Vol% formic acid)-gradient)) to yield 90 mg 2-(3,5-difluorophenyl)-6-(4-methylphenyl)-3-oxo-/V-(3,3,3-trifluoro-2-hydroxypropyl)-2,3- dihydropyridazine-4-carboxamide. 1H-NMR (400 MHz, DMSO-d6): delta = 2.37 (s, 3H); 3.47 (ddd, 1 H); 3.74 (ddd, 1 H); 4.17-4.28 (m, 1 H); 6.66 (d, 1 H); 7.34 (d, 2H); 7.47 (tt, 1 H); 7.53-7.58 (m, 2H); 7.87 (d, 2H); 8.64 (s, 1 H); 9.60 (t, 1 H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,431-38-9, its application will become more common.
