To a stirred solution of N-{3-[2-amino-6-(2-{[tert-butyl(dimethyl)silyl]oxy}phenyl)-3-cyano-4-pyridinyl]-phenyl}-3-(1-piperidinyl)propanamide (0.150 g, 0.270 mmol) in 1,4-dioxane (5 mL) was added 4N HCl in dioxane (2 mL). The mixture was stirred at room temperature for 12 hrs. The resulting precipitate was collected by filtration, washed with ethanol, and dried under reduced pressure to give N-{3-[2-amino-3-cyano-6-(2-hydroxyphenyl)-4-pyridinyl]phenyl}-3-(1-piperidinyl)propanamide hydrochloride (0.011 g, yield 9%).
