Ring opening of epoxide (I) with hydrogen fluoride-pyridine complex affords the fluorohydrin (II). After conversion of (II) to the corresponding tosylate (III), reaction with potassium phthalimide in boiling DMF furnishes the substituted phthalimide (IV). Hydrolysis of phthalimide (IV) in hot ethanolamine gives rise to the primary amine (V). Condensation of (V) with 5-methylpyridine-2-carbaldehyde (VI) leads to imine (VII). Finally, reduction of imine (VII) to the corresponding amine with methanolic KBH4, followed by conversion to the fumarate salt provides the title compound.
