Reference of 16681-70-2, These common heterocyclic compound, 16681-70-2, name is 1H-[1,2,3]Triazole-4-carboxylic acid, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a mixture of (E)-3-(4-chloro-2-((5-methyl-2 H-tetrazol-2-yl)methyl)phenyl)- 1 -(4-(pi peridi n-4- yl)piperazin-i-yl)prop-2-en-i-one, dihydrochloride salt (Example 149, step 2)(130 mg, 0.259 mmol), DIPEA (0.316 ml, 1.810 mmol) and 1H-i ,2,3-triazole-4-carboxylic acid (38.0 mg, 0.336 mmol) in DMF (1.5 ml) was added T3P, 50% solution in EtOAc (0.302 ml, 0.517mmol). The resultant mixture was stirred at room temperature over the weekend. Water (0.5 ml) was added and the solvent removed in vacuo. The residue was purified by reverse phase preparative HPLC to afford the title compound as the trifluoroacetate salt;LC-MS: Rt 0.87 mins; MS mlz 525.3 (M+H)+; Method 2minLowpHvo2
Statistics shows that 1H-[1,2,3]Triazole-4-carboxylic acid is playing an increasingly important role. we look forward to future research findings about 16681-70-2.
