実験手順
A mixture of methyl 5-chloro-6-methyl-2-pyrazine carboxylate (0.16 g, 0.86 mmol), K2CO3 (0.31 g, 2.18 mmol) and H2O was stirred for 2 h at room temperature. The reaction was filtered and acidified (20% HCl), and the resulting solid collected to provide the title compound (0.057 g, 39% yield); m.p. 116°-117° C.
