Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 27398-39-6, name is 3-Chloropyrazine-2-carboxylic acid, This compound has unique chemical properties. The synthetic route is as follows., Formula: C5H3ClN2O2

To a suspension of sodium hydride (278 mg, 6.95 mmol, 60percent in oil) in DMF (10 mL) was added 1H-pyrazole (279 mg, 4.11 mmol) at RT and the resulting mixture was stirred at room temperature for 30 mins. 3-Chloropyrazine-2-carboxylic acid (500 mg, 3.16 mmol) wasadded and the mixture heated to 60 °C for 2 h. After cooled to RT, water (20 mL) was added and the mixture extracted with 4.7percent MeOH in DCM (20 mL x 3). The combined organic layers were washed with brine, dried over Na2504, filtered, and concentrated in vacuo to give the title compound. LRMS m/z (M+H) 191.0 found, 191.0 required.
