Adding a certain compound to certain chemical reactions, such as: 104539-21-1, name is 1-Iodo-2-(2-methoxyethoxy)ethane, belongs to iodides-buliding-blocks compound, 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 104539-21-1, name: 1-Iodo-2-(2-methoxyethoxy)ethane
STR27 100 mg (0.240 mmol) of Compound 5 synthesised in Reference Example 4 was dissolved in 1.0 ml of anhydrous DMF. To this solution, 166 mg (1.20 mmol) of potassium carbonate and a solution of 276 mg (1.20 mmol) of 1-iodo-2-(2-methoxyethoxy)ethane in 0.5 ml of anhydrous DMF were added. This reaction mixture was stirred at room temperature for 8 hours and 25 minutes. The reaction mixture was then added to a saturated aqueous solution of sodium chloride. The mixture was then extracted with ethyl acetate. The extract layer was washed with a saturated aqueous solution of sodium chloride two times, dried over magnesium sulfate, and concentrated. The residue was chromatographed on silica gel and eluted with a mixed solvent of ethyl acetate and hexane (1:1), whereby ethyl (E)-7-[4′-fluoro-5-[2-(2-methoxyethoxy)ethoxy]-3-(propan-2-yl)biphenyl-2-yl]-3,5-dihydroxy-6-heptenoate (Compound 11) was obtained in the form of a colorless oil in a yield of 26 mg (20.9%). 1 H-NMR (300 MHz, CDCl3) delta 1.18-1.33(m, 1H), 1.21(d, J=6.8 Hz, 3H), 1.22(d, J=6.8 Hz, 3H), 1.28(t, J=7.1 Hz, 3H), 1.38-1.53(m, 1H), 2.33-2.50(m, 2H), 2.84(d, J=2.0 Hz, 1H), 3.23(hept, J=6.8 Hz, 1H), 3.39(s, 3H), 3.52-3.64(m, 2H), 3.61(d, J=2.3 Hz, 1H), 3.68-3.76(m, 2H), 3.80-3.92(m, 2H), 4.02-4.22(m, 3H), 4.18(q, J=7.1 Hz, 2H), 4.22-4.40(m, 1H), 5.19(dd, J=16.0 and 6.4 Hz, 1H), 6.51(d, J=16.0 Hz, 1H), 6.65(d, J=2.7 Hz, 1H), 6.88(d, J=2.7 Hz, 1H), 6.96-7.06(m, 2H), 7.16-7.24 m, 2H)ppm. IR (liquid film): 3456, 2964, 2932, 1736, 1602, 1512cm-1. Mass (m/z, %): 518 (M+, 52), 500 (32), 454 (93), 369 (32), 267 (32), 241 (36), 239 (43), 230 (15), 183 (20), 103 (57), 59 (100).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Iodo-2-(2-methoxyethoxy)ethane, other downstream synthetic routes, hurry up and to see.
