Society and culture

Dimethoxanate was introduced in Austria, Belgium, and France in 1911, and in Italy and Spain in 1963.[5] Approval for marketing in the US was withdrawn by the FDA in 1975 due to lack of evidence of efficacy.[6]

Synthesis

Synthesis:[7] Patent:[8]

Phenothiazine (1) is reacted with phosgene to give Phenothiazine-10-carbonyl chloride [18956-87-1] (2). Further reaction with 2-(2-(dimethylamino)ethoxy)ethanol [1704-62-7] (3) completed the synthesis of Dimethoxanate (4).
