Synthetic Route of 3641-13-2,Some common heterocyclic compound, 3641-13-2, name is 5-Amino-4H-1,2,4-triazole-3-carboxylic acid, molecular formula is C3H4N4O2, 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.
The organometallic complex [Mo(eta3-C3H5)Br(CO)2(NCMe)2]was prepared according to literature methods [1,5]. A solution of[Mo(eta3-C3H5)Br(CO)2(NCMe)2] (2.0 g, 5.63 mmol) in ethanol(60 mL) was treated with 3-amino-1,2,4-triazole-5-carboxylic acid(ATZAc) (0.72 g, 5.63 mmol). The resulting solution was stirred for8 h under reflux and evaporated to dryness. The solid obtained waswashed with hexane and dried under vacuum (1.98 g yield) [6].Elemental Analysis for MoC9O2BrN2H11 (354.94 g/mol): calculatedC 30.42%, N 7.88%, H 3.10%, Mo 27.03%; found C 30.28%, N 7.82%, H2.98%, Mo 26.95%. IR (KBr pellet, cm-1): nu (C?O) =1943-1857, nu (C=O) =1686. EDS (Full scale 22153 ct cursor: -0.348 (octs), keV):C, N, O, Br, Mo.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 5-Amino-4H-1,2,4-triazole-3-carboxylic acid, its application will become more common.
