Add a solution of borane-THF complex (4.5 mL, 4.54 mmol, 1M solution in THF) to neat 6-(iso-propoxy)methyl-pyridine-3-carbonitrile (0.4 g, 2.27 mmol) and stir the mixture for 16 h at reflux. Cool to room temperature and stir for 48 h. Add 2N aqueous HCl (10 mL) until gas evolution stops and then concentrate in vacuo. Dissolve the crude mixture in methanol and filter through a SCX-2 column eluting with methanol followed by 3N ammonia in methanol to obtain the title compound (190 mg, 46%).
