合成路线1
该中间体在本合成路线中的序号:(VI)This compound can be obtained by three different ways: 1) The reaction of 1-(p-chlorobenzoyl)-2-methyl-5-methoxy-3-indolylacetic acid (indomethacin) (I) with SOCl2 gives the corresponding acetyl chloride (II), which is treated with hydroxylamine hydrochloride and NaOH in water to afford 1-(p-chlorobenzoyl)-2-methyl-5-methoxy-3-indolylacetohydroxamic acid (III). Finally, this compound is hydrolyzed with 0.5 N NaOH in water. 2) The reaction of 1-(p-chlorobenzoyl)-2-methyl-5-methoxy-3-indolylacetal-dehyde (IV) with N-hydroxybenzenesulfonamide (V) in DMSO by means of NaOH yields compound (III) already obtained. 3) By reaction of tert-butyl-5-methoxy-2-methyl-3-indolylacetate (VI) with hydroxylamine in methanol.

合成路线2
该中间体在本合成路线中的序号:(IV)The condensation of cyclohexene-epoxide (I) with pyrrolidine (II) gives trans-2-(1-pyrrolidinyl)cyclohexanol (III), which by reaction with NaH and methanesulfonyl chloride, and then with benzylamine is converted into trans-2-(1-pyrrolidinyl)-N-benzylcyclohexylamine (IV). The debenzylation of (IV) by hydrogenolysis with H2 over Pd/C affords trans-2-(1-pyrrolidinyl)cyclohexylamine (V), which is formylated with ethyl formate to the corresponding N-formyl-trans-2-(1-pyrrolidinyl)cyclohexylamine (VI). The reduction of (VI) with LiAlH4 in refluxing ether gives trans-N-methyl-2-(1-pyrrolidinyl)cyclohexylamine (VII), which is finally condensed with 3,4-dichlorophenylacetic acid (VIII) by means of carbonyl diimidazole (IX) in THF.
