Application of 4774-14-5,Some common heterocyclic compound, 4774-14-5, name is 2,6-Dichloropyrazine, molecular formula is C4H2Cl2N2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A solution of compound 8 (450.0 g, 3.02 mol) in cone. aq. NH3 (3.0 L) was stirred at 135C overnight in a 10 L sealed pressure vessel. TLC and LC/MS showed complete conversion of the starting material. The reaction mixture was cooled to room temperature and filtered to afford a white solid. The solid was washed with water (200 mL x 3), and then dried to afford compound 9 (312 g, 80% yield) as a solid. 1HNMR (400 MHz, DMSO- 6): delta 7.82 (s, 1 H), 7.12 (s, 1 H), 6.93 (s, 2H). MS Calcd.: 129 MS Found: 130 ([M+H]+).
The synthetic route of 4774-14-5 has been constantly updated, and we look forward to future research findings.
