Related Products of 431-38-9, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.431-38-9, name is 3-Amino-1,1,1-trifluoropropan-2-ol, molecular formula is C3H6F3NO, molecular weight is 129.0811, as common compound, the synthetic route is as follows.
3-Oxo-2-(pyridin-3-yl)-6-[4-(trifluoromethyl)phenyl]-2 ,3-di hydropyridazi ne-4-carboxylic acid (100 mg, 0.277 mmcl) was dissolved in anhydrous DMF (2.1 mL). (2RS)-3-Amino-1,1,1- trifluoropropan-2-ol (71.5 mg, 0.55 mmol), N-ethyl-N-isopropylpropan-2-amine (314 pL, 1.80mmol), and propane phosphonic acid anhydride (T3P, 243 pL, 50% in DMF, 415 pmol) were successively added. It was stirred at rt overnight. The reaction mixture was diluted with dichloromethane and concentrated under vacuum. The residue was purified by RP-HPLC (column: X-Bridge 018 5pm lOOx3Omm, mobile phase: (water + 0.2 vol% aqueous ammonia (32%)) acetonitrile, gradient) yielding 57.3 mg (44%) of the title compound.1H-NMR (400MHz, DMSO-d6): 6 [ppm] = 3.49 (ddd, 1H), 3.76 (ddd, 1H), 4.18-4.29 (m, 1H),6.68 (br s, 1H), 7.65 (ddd, 1H), 7.89 (d, 2H), 8.18 (ddd, 1H), 8.22 (d, 2H), 8.71 (dd, 1H), 8.75(s, 1H), 8.93 (d, 1H), 9.59 (t, 1H).
Statistics shows that 431-38-9 is playing an increasingly important role. we look forward to future research findings about 3-Amino-1,1,1-trifluoropropan-2-ol.
