Alkylation of aminothiazoles
- 96 Downloads
The alkylation of 2-aminothiazole and 2-amino-4-methylthiazole with ten-butyl alcohol in sulfuric acid has been repeated. In correction of preceding information, it has been found that alkylation takes place in position 5 of the thiazole ring and not at the amino group. The presence of a primary amino group in the alkylation products was shown by the production of arylsulfonyl derivatives soluble in alkalies and of 2-halothiazoles by the Sandmeyer replacement of the amino group by halogen. Alkylation with alkyl halides yielded the corresponding thiazolone imides.
