Clomacran is an antipsychotic drug of the acridines class, developed in the 1970s[2] by the pharmaceutical company Smith, Kline & French under the brand names Devryl and Olaxin.[1]

It was been used to treat schizophrenia in the 70s.[6] It was withdrawn from the market in the UK, due to liver toxicity, in 1982.[5][7][8]

Synthesis

Patents:[9][10][11][12]

The first step involves FGI of 3-chloro-N,N-dimethylpropylamine Fb: [109-54-6] (2) into the Grignard reagent, i.e. (3-(Dimethylamino)propyl)magnesium chloride [19070-16-7] ([154034-91-0]). The Grignard reaction with 2-chloroacridone [7497-52-1] (1) affords the tertiary carbinol (3). Dehydration by means of acid or simply heat gives the corresponding olefin (4). Catalytic reduction completes the synthesis of the tranquilizer, clomacran (5).
