<unk>  is a tetracyclic piperazinoazepine; mianserin was developed by the same team of organic chemists and<unk>  differs from it via addition of a nitrogen atom in one of the rings. It is a racemic mixture of enantiomers. The (S)-(+)-enantiomer is known as esmirtazapine. Analogues of<unk>  include mianserin, setiptiline, and aptazapine. Synthesis A chemical synthesis of<unk>  has been published. The first step of synthesis is a condensation reaction between the molecule 2-chloro 3-cyanopyridine and the molecule 1-methyl-3-phenylpiperazine.
