The condensation of 4-methoxybenzylmagnesium chloride (I) with 3,4-dimethylpyridine methiodide (II) gives N,3,4-trimethyl-2-(p-methoxybenzyl)-1,2-dihydropyridine (III), which by partial reduction with NaBH4 in methanol is converted into the corresponding 1,2,5,6-tetrahydro derivative (IV). The cyclization of (IV) by refluxing with AlBr3 in CS2 yields 2,5,9-trimethyl-2'-hydroxy-7-benzomorphane (V), which is acetylated with acetic anhydride to the acetoxy compound (VI) and treated with BrCN in refluxing CHCl3 to afford the N-cyano compound (VII). This compound is refluxed with 6% HCl yielding 5,9-dimethyl-2'-hydroxy-6,7-benzomorphane (VIII) , which is condensed with 4-(p-fluorophenyl)-4,4-ethylenedioxy-1-chlorobutane (XVI) by means of NaHCO3 in DMF at 140 C to afford the corresponding N-alkyl derivative (IX). Finally, this compound is hydrolyzed by refluxing with diluted aqueous HCl.

The condensation of 4-chloro-1-(4-fluorophenyl)-1-butanone ethylene ketal (I) with 4-(2-nitroanilino)piperidine (III) by means of KI in refluxing butanol gives 1-[3-(4-fluorobenzoyl)propyl]-4-(2-nitroanilino)piperidine ethylene ketal (IV), which is reduced with H2 over Raney-Ni in methanol yielding the corresponding amino compound (V). Finally this compound is cyclized with CS2 by means of KOH in refluxing ethanol
