288-36-8, Adding some certain compound to certain chemical reactions, such as: 288-36-8, name is 1H-1,2,3-Triazole, 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 288-36-8.
2-(2H-l,2,3-Triazol-2-vD-5-methylbenzoic acid (1-7)A solution of 2-iodo-5-methylbenzoic acid (4.0 g, 15.3 mmol) in DMF (10 mL) was treated with 1,2,3-triazole (2.1 g, 30.5 mmol), CsCO3 (9.95 g, 30.5 mmol), CuI (0.145 g, 0.76 mmol) and trans-N,N’-dimethylcyclohexane-l,2-diamine (0.43 g, 3.05 mmol). The mixture was heated at 120 0C for 10 min in a microwave reactor. The reaction was cooled to room temperature, diluted with water, and washed with EtOAc. The aqueous phase was acidified with IN HCl and extracted with EtOAc. The organic layer was dried over Na2SO4, filtered and concentrated. The residue was purified by gradient elution on SiO2 (0 to 10% MeOH in water with 0.1% AcOH) to give the faster eluting 2-(2H-l,2,3-triazol-2-yl)-5-methylbenzoic acid 1-5. followed by the undesired regioisomer isomer, l-(2H-l,2,3-triazol-2-yl)-5-methylbenzoic acid. Data for K7: 1HNMR (500 MHz, DMSO-d6) d 12.98 (br s , IH), 8.04 (s, 2H), 7.72-7.45 (m, 3H), 2.41 (s, 3H) ppm.
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 288-36-8.
