Synthesis of intermediate (X): 4-Hydroxypiperidine (V) is protected with ethyl chloroformate to give (VI), which is then condensed with bromodiphenylmethane in the presence of sodium carbonate yielding (VII). AIkali hydrolysis of (VII) gives (VIII), which is then treated with N-(2-bromoethyl)phthalimide to yield (IX). (IX) is then deprotected by a treatment of 80% hydrazine hydrate, producing (X).
