Extended knowledge of 570-22-9

The synthetic route of 570-22-9 has been constantly updated, and we look forward to future research findings.

Synthetic Route of 570-22-9, These common heterocyclic compound, 570-22-9, name is 1H-Imidazole-4,5-dicarboxylic 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.

In a dried f[ask, to 25 g (157 mmo[) 1H-imidazo[e-4,5-dicarboxy[ic acid in 334 mL of to[uene, 12.1 mL DMF and 94 mL (1.29 mo[) thiony[ ch[oride were added. The mixture was stirred for 24 h at 80C.The mixture was concentrated under reduced pressure. 100 mL to[uene were added and the mixture was concentrated under reduced pressure to give 35.5 g of thetit[e compound as crude materia[ which was used at the same day without further purification for subsequent steps.

The synthetic route of 570-22-9 has been constantly updated, and we look forward to future research findings.
