Reaction Steps

To a stirred solution of tert-butyl 4-[2-amino-6-[2-(cyclopropylmethoxy)-6-hydroxyphenyl]-3-(1H-imidazol-1-ylmethyl)-4-pyridinyl]-1-piperidinecarboxylate (0.260 g, 0.500 mmol) in 1,4-dioxane (10 mL) was added 4N HCl in dioxane (10 mL). The mixture was stirred at room temperature for 2 hrs. The resulting precipitate was collected by filtration, washed with acetonitrile, and dried under reduced pressure to give 2-[6-amino-5-(1H-imidazol-1-ylmethyl)-4-(4-piperidinyl)-2-pyridinyl]-3-(cyclopropylmethoxy)phenol hydrochloride. (0.248 g, yield; quant.)
