Electric Literature of 55984-93-5, A common heterocyclic compound, 55984-93-5, name is 2-Methylterephthalonitrile, molecular formula is C9H6N2, 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.
Into a 250-mL round-bottom flask, which was purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 2-methylbenzene-l,4-dicarbonitrile (4 g, 28.14 mmol, 1.00 equiv), [(tert-butoxy)(dimethylamino)methyl]dimethylamine (9.8 g, 56.23 mmol, 2.00 equiv) in N,N-dimethylformamide (50 mL). The resulting solution was stirred overnight at 75 °C, and then concentrated under vacuum. The resulting mixture was washed with 50 mL of hexane. The solids were collected by filtration. This provided 5.3 g (95percent) of 2-[(E)-2- (dimethylamino)ethenyl]benzene-l,4-dicarbonitrile as a yellow solid.
The synthetic route of 55984-93-5 has been constantly updated, and we look forward to future research findings.
