Procedure

2-Methyl-propane-2-sulfinic acid{1-[6-(6-hydroxymethyl-pyridin-3-yl)-pyridazin-3-yl]-1-methyl-ethyl}-amide (4 mg, 0.011 mmol) was dissolved in CH2Cl2 (0.25 mL) and 4M HCl in dioxane (2 mL, 8 mmol) was added. After 45 minutes, the solvent was removed under a stream of N2 to give {5-[6-(1-amino-1-methyl-ethyl)-pyridazin-3-yl]-pyridin-2-yl}-methanol dihydrochloride as a crude light brown solid residue. This was used without further purification.
