Application of 2240-88-2, 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.2240-88-2, name is 3,3,3-Trifluoropropan-1-ol, molecular formula is C3H5F3O, molecular weight is 114.07, as common compound, the synthetic route is as follows.
Example 98 (5a,8 )-8-Hydroxy-2-[4-(3,3,3-trifiuoro-propoxy)-phenyl]-2-aza-spiro[4.5]decan-l-oneStep 1: l-Nitro-4-(31313-trifluoro-propoxy)-benzeneTo a solution of a 3,3,3-trifiuoro-propan-l-ol (6.22 g) in acetonitrile (200 ml) kept at RT under an argon atmosphere were added l-fiuoro-4-nitro-benzene (10.1 g) and Cs2C03 (28.7 g) and the mixture was heated to 100°C for 18 h. The reaction mixture was cooled to RT and partitioned between AcOEt and ice water. The layers were separated, dried, over Na2S04 and the solvent was evaporated. The residue was purified by flash chromatography (silica gel; eluent: AcOEt/heptane: gradient 3 to 5 percent) to afford l-nitro-4-(3,3,3-trifiuoro- propoxy) -benzene as light yellow liquid (3.5 g). MS (EI, m/e): 235.0 (M+).
Statistics shows that 2240-88-2 is playing an increasingly important role. we look forward to future research findings about 3,3,3-Trifluoropropan-1-ol.
