yellow crystalline powder | [Uses]
Methyl 3-amino-2-pyrazinecarboxylate has been used in:
- synthesis of 2-arylpteridin-4-ones and piperazine-derived 2-furan-2-yl-[1,2,4]triazolo[1,5-a] pyrazines
- reactions with isocyanates and aroyl chlorides for conversion to pteridinediones
| [Definition]
ChEBI: Methyl 3-aminopyrazine-2-carboxylate is a pyrazine that is substituted by a methoxycarbonyl group at position 2 and an amino group at position 3. It is a member of pyrazines, a methyl ester and an aromatic amine. | [storage]
Store at -20°C | [Purification Methods]
The ester forms yellow needles from H2O (100 parts using charcoal). If it contains the free acid (see IR), then dissolve it in CH2Cl2, wash it with saturated aqueous Na2CO3, brine, dry over MgSO4 filter, evaporate and recrystallise the residue. The free acid has m 203-204o (dec) [UV: Brown & Mason J Chem Soc 3443 1956] and pK1 <1 and pK2 3.70. The ammonium salt has m 232o(dec) (from aqueous Me2CO) and the amide has m 239.2o (from H2O) [Ellingson et al. J Am Chem Soc 67 1711 1945]. [Beilstein 25 III/IV 4412.] |
