该中间体在本合成路线中的序号:(XXII)In an alternative synthesis, phenylacetaldehyde (XVIII) was condensed with pyrrolidine (XIX) to give enamine (XX). Nitrosation of malononitrile (XXI), followed by treatment with tosyl chloride, produced the O-tosyl oxime (XXII). This was condensed with enamine (XX), and to the intermediate adduct (XXIII) was added thiophenol producing the phenylthiopyrazine (XXIV). Subsequent oxidation of the sulfide group of (XXIV) to sulfone (XXV), followed by condensation with methyl thioglycolate, gave the desired thienopyrazine (XIII).
