Related Products of 6629-04-5, A common heterocyclic compound, 6629-04-5, name is N-Cyanoacetylurethane, molecular formula is C6H8N2O3, 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.
General procedure: To the mixture of substituted anilines (0.08mol), concentrated hydrochloric acid (45.0mL) and water (120.0mL), aqueous solution of NaNO2 (60.0mL, 0.11mol) was added drop-wise under stir at a rate that the temperature below 0C, and the reaction mixture was stirred for 0.5h. A mixture of ethyl (2-cyanoacetyl)carbamate (13.7g, 0.09mol) and sodium acetate (24.0g, 0.27mol) in ethanol (400.0mL) was added drop-wise to the resulting diazonium salt solution below 0C and stirred for a further 2h. The precipitate was collected by filtration and washed with water (40.0 mL¡Á2), dried to give compounds 7a-f.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
