The reaction of 3,5-dichloro-6-methoxysaliclic acid (I) with refluxing SOCl2 gives the corresponding acyl chloride (II), which is condensed with 1-ethyl-2-(aminomethyl)pyrrolidine (III) in methylene chloride yielding the amide (IV). Finally, this compound is partially demethylated with BBr3 in methylene chloride ether.
