Reaction Steps

A solution of N-(4-chlorophenyl)-2-[1-(4-pyridyl)-piperidin-4-ylmethyl]aminopyridine-3-carboxamide (25 mg, 0.059 mmol) in THF (1 mL) was treated with lithium aluminum hydride (1.0 M in THF, 0.21 mL, 0.21 mmol). The mixture was heated at 65° C. for 4 days, cooled, diluted with methanol (5 mL), and loaded onto an SCX ion exchange resin. The resin was eluted with methanol followed by 2 N NH3 in methanol and fractions containing the desired material were concentrated. The residue was triturated with EtOAc, yielding 15 mg (62%) of the title compound.
