Reaction Steps

Next, the bromophenoxypiperidine intermediate is aminated at the benzo 3-position, as for example, by reacting the intermediate with (±)BINAP, Pd2(dba)3, benzhydrylideneamine, and sodium tertbutoxide in a suitable solvent, such as toluene or the like, under an inert atmosphere for about 1 to about 3 hrs., say about 2 hours, at about 50° C. to 100° C., say about 80° C. The resulting 3-(piperidin-4-yloxy)-phenylamine intermediate may then be isolated and purified by common procedures such as, but not limited to, solvent removal, extraction, and/or chromatography, etc.
