Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 34270-90-1, name is 1-Iodo-2-(2-iodoethoxy)ethane, This compound has unique chemical properties. The synthetic route is as follows., Application In Synthesis of 1-Iodo-2-(2-iodoethoxy)ethane
A N,N-dimethylformamide (0.5 mL) solution of (ls,4s)-4-(4-(2-((2,6- difluorobenzyl)oxy)- 1,1,1 ,3 ,3 ,3 -hexafluoropropan-2-yl)phenyl)-4-((4- fluorophenyl)sulfonyl)cyclohexanamine (10 mg, 0.016 mmol), l-iodo-2-(2- iodoethoxy)ethane (15.63 mg, 0.048 mmol) and potassium carbonate (26 mg, 0.188 mmol) was stirred at room temperature for 3 days. LCMS analysis showed that the reaction was near completion. The mixture was diluted with ethanol (1 mL) and filtered. The crude material was purified via preparative LC/MS with the following conditions: Column: Waters XBridge CI 8, 19 x 250 mm, 5-muiotaeta particles; Mobile Phase A: 5:95 acetonitrile: water with 10-mM ammonium acetate; Mobile Phase B: 95:5 acetonitrile: water with 10-mM ammonium acetate; Gradient: 40-100% B over 25 minutes, then a 5- minute hold at 100% B; Flow: 20 mL/min. Fractions containing the desired product were combined and dried via centrifugal evaporation to give Example 8 (4.5 mg, 36% yield). LC/MS (M+l): 696.3; LC retention time: 2.46 min (analytical HPLC Method B); 1H NMR (400 MHz, 1 : 1 mixture of CDC13-CD30D) delta ppm 7.60 (d, J=8.4 Hz, 2H), 7.43 – 7.34 (m, 3H), 7.24 (dd, J=8.9, 5.1 Hz, 2H), 7.02 – 6.90 (m, 4H), 4.73 (s, 2H), 3.79 (br. s., 3H), 2.81 (d, J=8.1 Hz, 2H), 2.51 (br. s., 3H), 2.28 – 2.06 (m, 5H), 1.46 – 1.20 (m, 4H).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 34270-90-1.
