In an article, published in an article,authors is Bach, Thorsten, once mentioned the application of 4175-77-3, Name is 2,4-Dibromothiazole,molecular formula is C3HBr2NS, is a conventional compound. this article was the specific content is as follows.4175-77-3
The difunctional substrate 2,4-dibromothiazole 2 was transformed into the title compounds 1 by consecutive Pd(0)-catalyzed cross-coupling reactions. Aryl zinc reagents which were prepared by ortho-lithiation of compounds 3 and subsequent transmetalation were used as carbon nucleophiles in the first coupling reaction. By this means, an aryl substituent was attached to the 2-position (50-62% yield). A succeeding cross-coupling with arylboronic acids 4 occurred at the 4-position of the intermediate 4- bromothiazoles 5 (76-97% yield). (C) 2000 Elsevier Science Ltd.
