6164-79-0, Name is Methyl 2-pyrazinecarboxylate, 6164-79-0, belongs to Pyrazines compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows.
d Pyrazine-2-hydrazide To a solution of the product from Example 1 step c) (22 g, 159 mmol) in methanol (250 ml) was slowly added hydrazine monhydrate (36.6 ml, 710 mmol). The reaction mixture was stirred for 1.5 h. The precipitate produced was filtered, washed with diethyl ether and dried in the oven at 80 C. to give the required product (30 g). 1H NMR (250 MHz, DMSO) delta 4.66 (2H, broad peak), 8.66 (1H, m), 8.84 (1H, d, J=2.5 Hz), 9.13 (1H, d, J=2.5 Hz), 10.15 (1H, broad peak); MS (ES+) m/e 139 [MH+].
Statistics shows that Methyl 2-pyrazinecarboxylate is playing an increasingly important role. we look forward to future research findings about 6164-79-0.
