Lenperone (Elanone-V) is a typical antipsychotic of the butyrophenone chemical class.[1] It was first reported as an anti-emetic in 1974,[2] and its use in treatment of acute schizophrenia was reported in 1975.[1] Related early antipsychotic agents include declenperone and milenperone.

Lenperone was never approved by the FDA for use in humans in the United States,[3] but prior to 1989 it was approved for use in veterinary medicine for sedation.[4][5][6]

Synthesis

Synthesis (cmp#21):[7] Patent (74%):[2] Enbodiment 19 (62%):[8][9]

The alkylation between 2-(3-chloropropyl)-2-(4-fluorophenyl)-1,3-dioxolane [3308-94-9] (1) and 4-(4-fluorobenzoyl)piperidine [56346-57-7] (2) gives 2-(p-fluorophenyl)-2-{3-[4-(p-fluorobenzoyl)piperidino]propyl}-1,3-dioxolane, CID:20318874 (3). Deprotection of the ketal function completes the synthesis of lenperone (4).
