The Name is Pyrazine-2-carboxylic acid. Through research, I have a further understanding and discovery of 98-97-5.
A highly efficient and simple procedure for the synthesis quinoline-3-carboxamides and their analogues via amidation reaction of quinoline-3-carboxylic acids with tetraalkylthiuram disulfides has been developed. The reaction proceeds efficiently under simple reaction conditions and features the generality of broad scope of substrates with good yields. This protocol provides a convenient procedure for the synthesis of various aza-heteroaromatic carboxamides, which is of pharmaceutical interest.
