合成路线1
该中间体在本合成路线中的序号：(VI)The reaction of o-chlorophenylacetic acid (I) with SOCl2 gives the corresponding acyl chloride (II), which is condensed with 2-(methylamino) ethanol (III) yielding o-chloro-N-methyl-N-(2-hydroxyethyl)phenylacetamide (IV). The reduction of (IV) with diborane in THF affords N-methyl-N-(2-hydroxyethyl)-2-(2-chlorophenyl)ethylamine (V), which by reaction with PCl5 in CHCl3 is con-verted into N-methyl-N-(2-chloroethyl)-2-(2-chlorophenyl)ethylamine (VI). Finally, this compound is cyclized by means of anhydrous AlCl3-NH4Cl at 175 C.
