Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 108-13-4, name is Malonamide, A new synthetic method of this compound is introduced below., Formula: C3H6N2O2
[0533] Into a 3000-mL 3-necked round-bottom flask were placed a solution of sodium ethoxide (155 g, 2.28mol, 4.00 equiv) in ethanol (2000 mL), malonamide (233 g, 2.28mol, 4.00 equiv) and 5-chloro-l,3-dimethylpyrimidine-2,4(lH,3H)-dione (100 g, 571.43 mmol, 1.00 equiv). The resulting solution was heated to reflux for 20 min. Then it was cooled and concentrated under vacuum. The residue was diluted with 500 mL of H20, and then adjusted to pH 2 with HCl. The solid was collected by filtration and dried in an oven under reduced pressure. This resulted in 50 g (crude) of 5-chloro-2,6-dihydroxynicotinamide as a white solid.
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.
