78818-15-2,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.78818-15-2,Benzyl 3-oxopiperazine-1-carboxylate,as a common compound, the synthetic route is as follows.
Reference Example 17 4-Benzyloxycarbonyl-1-[4-(tert-butoxycarbonylamino)benzyl]-2-piperazinone According to a similar method described in Reference Example 2, the title compound of pale yellow amorphous was obtained from 4-benzyloxycarbonyl-2-piperazinone and 4-(tert-butoxycarbonylamino)benzylbromide. 1H-NMR (CDCl3) delta: 1.51 (9H, s), 3.23 (2H, t, J=5.2 Hz), 3.63 (2H, t, J=5.3 Hz), 4.22 (2H, s), 4.55 (2H, s), 5.15 (2H, s), 7.10-7.40 (10H, m). IR (KBr): 1707, 1655, 1530, 1235, 1163 cm-1.
As the paragraph descriping shows that 78818-15-2 is playing an increasingly important role.
