Procedure

The resulting methyl 2-(5-(4-(2-morpholinoethoxy)phenyl)pyridin-2-yl)acetate (7) and benzyl amine were coupled in anisole at high temperature to afford 2-(5-(4-(2-morpholinoethoxy)phenyl)pyridin-2-yl)-N-benzylacetamide (KX2-391). An HCl solution formed by adding acetyl chloride to absolute ethanol was added to KX2-391 to form the bis-HCl salt, 2-(5-(4-(2-morpholinoethoxy)phenyl)pyridin-2-yl)-N-benzylacetamide dihydrochloride, (KX2-di-HCl).
