合成路线1
该中间体在本合成路线中的序号：(XV)7) [12b-14C]-Org-5222: The condensation of labeled sarcosine methyl ester (XVI) (prepared from sarcosine (XV) with SOCl2 and methanol) with 2-(5-chloro-2-phenoxyphenyl)acetyl chloride (XVIII) (prepared from the corresponding acid (XVII) and SOCl2) yields the acylated sarcosine (XIX), which is cyclized by means of potassium tert-butoxide in toluene to the pyrrolidinedione (XX). A further cyclization of (XX) with polyphosphoric acid affords [3a-14C]-11-chloro-2-methyl-2,3-dihydro-1H-dibenz[2,3:6,7]oxepino[4,5-c]pyrrol-1-one (XXI), which is reduced with Mg in methanol to the trans-isomeric amide (XXII) (along with the cis-isomer, which is separated by HPLC). Finally, the amide (XXII) is reduced with LiAlH4/AlCl3 in ethyl ether.
