Related Products of 3616-56-6, These common heterocyclic compound, 3616-56-6, name is 2,2-Diethoxy-N,N-dimethylethanamine, 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.
Synthesis example B6: Synthesis of 12H-benzofuranyl[3,2-a]carbazole (compound 6); (6); Compound 5 (2.8 g, 1 eq.) is added to acetic acid (30 ml) and heated to reflux. (Dimethylamino)acetaldehyde diethyl acetal (95percent; 20.3 g, 10 eq.) is added dropwise in portions to the solution. The reaction is stirred at reflux overnight. Then further (dimethylamino)acetaldehyde diethyl acetal (95percent; 2.0 g) is added and stirred further at reflux after 3 h. Subsequently, the flask contents are diluted with CH2CI2 at room temperature and washed in a separating funnel with distilled water and NaCI (saturated). Organic phase is dried with Na2S04 and concentrated. LC (Si02, 15:85 ethyl acetate/cyclohexane) gives the product 6 (1 .92 g, 62.2percent yield).1 H NMR (CD2CI2, 400 MHz): “5 = 8.88 (br s, 1 H), 8.16 (d, 1 H), 8.12 (d, 2H), 7.66 (d, 1 H), 7.62 (d, 1 H), 7.42-7.53 (m, 4H), 7.31 (dd, 1 H).
The synthetic route of 3616-56-6 has been constantly updated, and we look forward to future research findings.
