An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.7025-19-6, name is 3-(4-Oxo-2-thioxothiazolidin-3-yl)propanoic acid. Here is a downstream synthesis route of the compound 7025-19-6. 7025-19-6
5908-62-3, Example 60: 5-{5-[(3-{(1R,5S/1S,5R)-1-[4-(1,1-Dioxido-2-isothiazolidinyl)phenyl]-3- azabicyclo [3. 1.0] hex-3-yl} propyl) thio]-4-methyl-4H-1, 2, 4-triazol-3-yl}-2- methylquinoline hydrochloride; A Schlenk tube was charged with 5-[5-({3-[(1R,5S/1S,5R)-1-(4-bromophenyl)-3- azabicyclo [3.1. 0] hex-3-yl] propyl} thio)-4-methyl-4H-1, 2, 4-triazol-3-yl]-2-methylquinoline (cf. Example 2; 0.15 g), isothiazolidine 1,1-dioxide (46 mg), tris (dibenzylideneacetone)- dipalladium (0) (6 mg), 4,5-bis (diphenylphosphino)-9, 9-dimethylxanthene (10 mg), cesium carbonate (130 mg) and 1,4-dioxane (2 mL). The Schlenk tube was sealed with a teflon screwcap and the reaction mixture was stirred at 100 C for 12 h. The reaction mixture was allowed to cool to room temperature, diluted with dichloromethane (10 mL), filtered and concentrated in vacuo. The crude product was purified by flash chromatography (dichloromethane to 10% MeOH in dichloromethane) to give 50 mg of the free base of the title compound. To a solution of this material in dichloromethane (0.3 mL) was added HCI (0.087 mL, 1 M in Et20), the solvent evaporated in vacuo and the material thus obtained triturated with Et20 to give 52 mg of the title compound as a white solid. NMR (‘H, DMSO): 8 10.57 (bs, 1H), 8.27 (bd, 1H), 8.19 (d, 1H), 7.94 (t, 1H), 7.82 (d, 1H), 7.55 (d, 1H), 7.32 (d, 2H), 7.18 (d, 2H), 4.03 (dd, 1H), 3.72 (m, 3H), 3.60/3. 20 (bm, 8H), 3.45 (s, 3H), 2.75 (s, 3H), 2.41 (m, 2H), 2.25 (m, 2H), 2.14 (m, 1H), 1.66/1. 10 (t/m, 2H). MS (m/z) : 575 [MH] +.
