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. 52548-14-8, name is 2-Iodo-5-methylbenzoic acid, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 52548-14-8
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 DCM with 0.1% AcOH) to give the faster eluting 2-(2H-l,2,3-triazol~2-yl)-5-methylbenzoic acid, followed by the undesired regioisomer isomer, I -(2H- 1 ,2,3-triazoI-2-yl)-5-methylbenzoic acid. A solution of the acid (3.56 g, 17.52 mmol) in 150 mL of DCM was stirred and cooled to O0C. The solution was treated with oxalyl chloride (1.9 mL, 21.9 mmol) and DMF (68 muL, .878 mmol). The solution was slowly warmed to room temperature and stirred overnight. Solvent was concentrated and the resulting solid was azetroped with DCM and concentrated to provide A-7 as a yellow solid.
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 52548-14-8.
