With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1122-63-0,1-(Pyridazin-3-yl)ethanone,as a common compound, the synthetic route is as follows.
Step 1 1-Methoxy-2-(pyridazin-3-yl)propene Prepared according to the method of Example 12, Step 1, using 3-acetylpyridazine. 1 H NMR (360 MHz, CDCl3) delta 2.15 (3H, d, J=1.3 Hz), 3.78 (3H, s), 6.49 (1H, d, J=1.2 Hz), 7.33 (1H, dd, J=8.8 and 4.8 Hz), 8.16 (1H, dd, J=8.8 and 1.6 Hz), 8.95 (1H, dd, J=4.8 and 1.6 Hz)., 1122-63-0
As the paragraph descriping shows that 1122-63-0 is playing an increasingly important role.
