Homofenazine is an antipsychotic drug of the phenothiazines class.[5] It was synthesized by Wilhelm Schuler and colleagues at Degussa.[7][8] In 1966, it was released in Belgium under the brand name Pasaden.[1] At some point, it was quietly discontinued and is no longer marketed.[citation needed]

Synthesis

Thieme Patents (Ex 5&6):[9][10]

The alkylation between 2-(Trifluoromethyl)Phenothiazine [92-30-8] (1) and 1-(3-bromopropyl)-1,4-diazepane (2) led to 10-[3-(1,4-diazepan-1-yl)propyl]-2-(trifluoromethyl)phenothiazine, CID:110174391 (3). Further alkylation with 2-Chloroethanol [107-07-3] (4) completed the synthesis of homofenazine (5).
