Method for preparing 3 - amino -2, 4 -dimethylthiophene (by machine translation)

The invention relates to the field, and relates to the field of chloroacetamide preparation. The invention discloses a preparation method, namely 3 -) and -2 dimethylamino 4 - and the method comprises the following steps, 1) cyclization decarboxylation 2, 5 -dimethyl -3 -thiobenzoic acid, 2, 4 -dimethyl tetrahydrothiophene -3 - ketone; 2) rearrangement to obtain 2 amino 4 -3 -dimethylthiophene after condensation with hydroxylamine or a salt thereof in the presence of an acid 3 - anhydride -2 and 4 - a base in the presence of an acid anhydride and a base. By the method, the yield is high, and the yield is high. The preparation method of-amino,dimethylthiophene is suitable for large-scale production. 3 -2 4 . (by machine translation)
