Monatepil is a calcium channel blocker and α1-adrenergic receptor antagonist used as an antihypertensive.[1]

Synthesis

Synthesis:[2] Patent:[3]

Acylation of [1745-53-5] (1) with 4-chlorobutyryl chloride [4635-59-0] (2) then leads to the corresponding amide 4-Chloro-N-(5,11-dihydro-10-thia-dibenzo[a,d]cyclohepten-5-yl)-butyramide [103379-37-9] (3). Alkylation with para-Fluorophenylpiperazine [2252-63-3] (4) then completed the synthesis of monatepil (5).
