A common compound: 21948-70-9, name is 2-Methylthiopyrazine, belongs to Pyrazines compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 21948-70-9
To a mixture of 2-(methylthio)pyrazine (59 mg, 0.46 mmol) and CuI (44.5 mg,0.23 mmol), MeCN (5 mL) was added and the suspension was stirred at ambient temperature for 1 h. The precipitated redorangepowder was centrifuged and re-crystallized from acetonitrile to give 36 mg (35%) of 1. FT-IR (KBr, cm-1): 376 (w),397 (w), 413 (w), 434 (w), 484 (m), 633 (w), 648 (w), 723 (m), 762 (vs), 964 (m), 1007 (m), 1053 (m), 1094 (m), 1130 (m),1159 (s), 1263 (m), 1375 (m), 1420 (s), 1456 (s), 1560 (m), 1584 (s), 2922 (w), 2963 (w), 2982 (w), 3061 (w), 3098 (w).Anal. Calcd (%) for C20H24Cu2I2N8S4: 27.1, 2.7, N 12.6, S 14.5. Found: 27.0, 2.9, N 12.5, S 14.7.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 21948-70-9, other downstream synthetic routes, hurry up and to see.
