Procedure

As shown in scheme 7, 4-Hydroxybenzaldehyde is treated with potassium carbonate and 2,5-dibromopyridine in DMAC to afford 4-(5-bromo-pyridin-2-yloxy)-benzaldehyde (35). The aldehyde 35 is combined with isoamylamine, sodium triacetoxyborohydride, acectic acid, and dichloromethane to yield the reductive amination product [4-(5-bromo-pyridin-2-yloxy)-benzyl]-(3-methyl-butyl)-amine (36). The resulting aryl bromide 36 is treated with acetamide, copper iodide, and 1,2 diaminocyclohexane in dioxane to yield the target compound 37.
