Dimethylamine → 3-{2-[(2-Dimethylaminomethyl-4-thiazolyl)methylthio]ethylamino}-4-dimethylamino-1,2,5-thiadiazole 1-oxide

Participants

Reaction Steps

When a solution of 3,4-dimethoxy-1,2,5-thiadiazole 1-oxide [prepared in Example 4, Step A] is reacted with one equivalent of 2-[(2-dimethylaminomethyl-4-thiazolyl)methylthio]ethylamine [prepared in Example 33, Step E] and the resultant 3-}2-[(2-dimethylaminomethyl-4-thiazolyl)methylthio]ethylamino}-4-methoxy-1,2,5-thiadiazole 1-oxide is treated with an excess of dimethylamine according to the procedure described in Example 28, the title compound is thereby produced.
