Some common heterocyclic compound, 645-36-3, name is 2,2-Diethoxyethanamine, molecular formula is C6H15NO2, 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. HPLC of Formula: C6H15NO2
[00114] To a glass reactor was charged 3,5-dichlorobenzaldehyde. Absolute ethanol was added to the batch slowly (this addition is mildly exothermic) and agitation started. 2,2- Diethoxyethylamine (1.03 equiv) was slowly added to the batch, keeping the batch temperature at 20-78 C. The batch was then heated to 76-78 C for 2 h. GC-MS analysis indicated reactioncompletion (starting material < 1%). The batch was cooled to ambient temperature for work-up. The batch was concentrated in vacuo to a residue and azeotroped with heptanes (x2). The residue was cooled and held at 0-5 C for 12 h to form a suspension. The solids were collected by filtration and the cake was washed with cold (0-5 C) heptanes, and dried under hot nitrogen (45-5 0 C) to afford Compound 2? as a white solid (94% yield).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 645-36-3, its application will become more common.
