Procedure:
To a solution of 4-aminomethyl-4-hydroxy-1-(6-oxo-6-phenylhexyl)-piperidine dihydrochloride (2.9 g) in dimethylformamide (50 ml) were added triethylamine (3.2 ml), 4-amino-5-chloro-2-methoxybenzoic acid (1.55 g) and 1-hydroxybenzotriazole (1.09 g), which was followed by the addition of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (1.55 g) under ice cooling, and the mixture was stirred at room temperature for 6 hr. The reaction mixture was concentrated under reduced pressure, and the obtained residue was added with water and extracted with chloroform. The organic layer was washed successively with 10% aqueous solution of potassium carbonate and brine, and dried. The solvent was evaporated under reduced pressure, and the obtained residue was purified by a silica gel column chromatography (chloroform:methanol=10:1) to give 2.98 g of 4-amino-5-chloro-N-((4-hydroxy-1-(6-oxo-6-phenylhexyl)-piperidin-4-yl)methyl)-2-methoxybenzamide.

Procedure:
Sodium hydride (60% oil dispersion) (7.8 g) was added portionwise to a ice-water cooled solution of o-cresol (21.1 g) in tetrahydrofuran (500 mL). The mixture was stirred 20 minutes and then 1-(bromomethyl)-2-iodobenzene (58 g) was added. The mixture was warmed to 60° C. for 16 h. Additional sodium hydride (2 g) was added and the reaction mixture heated for an additional 3 h. The reaction mixture was cooled and carefully quenched with water and extracted with ethyl acetate (2×250 mL). The combined organic extracts were dried (MgSO4), filtered and concentrated under reduced pressure to an oil, which was triturated with cold hexane to provide a solid which was collected by filtration to yield 59.1 g (94%) of the title compound of Step B as a white solid, mp 106-108° C.
