合成路线1
该中间体在本合成路线中的序号:(XVIII)The hydrolysis of 3-(2-fluorophenyl)-5-chloroindole-2-carboxylate (XII) with KOH in refluxing ethanol affords the corresponding free acid (XVI), which by treatment with refluxing SOCl2 is converted into the acyl chloride (XVII). The reaction of (XVII) with NH3 in ether yields the amide (XVIII), which by N-alkylation with cyclopropylmethyl bromide (A) by means of NaH in DMF gives rise to the alkylated amide (VII) already obtained.

合成路线2
该中间体在本合成路线中的序号:(XVIII)The dehydration of the amide (XVIII) with refluxing POCl3 gives the corresponding nitrile (XIX), which by reduction with LiAlH4 in ether is converted into the 2-aminomethyl derivative (XX). The treatment of (XX) with CrO3 in acetic acid yields 5-(2-fluorophenyl)-7chloro-1,3-dihydro-2H-1,4-benzodiazepin-2-one (XXI) (1,10), which is finally N-alkylated with cyclopropylmethy bromide (A) by means of phenyllithium in THF.
