3616-56-6, 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. 3616-56-6, name is 2,2-Diethoxy-N,N-dimethylethanamine, A new synthetic method of this compound is introduced below.
5.0 g (20.0 mmol) of the intermediate (A-11), 4.8 g (30.0 mmol) of (dimethylamino)acetaldehyde diethylacetal, and 78 ml of acetic acid were loaded and the mixture was stirred for 96 hr while being heated at 140¡ãC. The reaction solution was cooled to room temperature and then the solvent was removed by evaporation under reduced pressure. The resultant residue was purified by silica gel column chromatography to give 2.3 g (8.4 mmol, yield: 42 molpercent) of an intermediate (A-12). FD-MS, m/z 274 [M]
