1. From 3,4-bischloromethyl-2,4-dimethylthiophene, by the action of suitable reagents, the following were prepared: 2,5-dimethyl-3,4-thiophenedimethanol diacetate (II), 2,5-dimethyl-3-4-thiophenedimethanol (III), 2,5-dimethyl-3,4-thiophenediacetonitrile (IV), 3,4-bisethoxymethyl-2,5-dimethylthiophene (V), and 2,5-dimethyl-3,4-thiophenediacetic acid (VI). 2. Hydrolysis of the hexamine salt formed by 3,4-bischloromethyl-2,5-dimethylthiophene with hexamethylenetetramine gave not the symmetrical diamine, but N, 2,5-trimethyl-3,4-thiophenebismethylamine. 3. An intermediate product formed in the course of the formation of the diamine has the composition C11H16N2OS, and its structure is probably
