Procedure

To a solution of 2-methyl-propane-2-sulfinic acid [(S)-1-(2-methanesulfonyl-pyridin-4-yl)-propyl]-amide (26 g, 82 mmol) in methanol (150 mL) was added a solution of 4 N HCl in dioxane (22.5 ml, 89.8 mmol) and stirred for 1 hour. The solution was concentrated to half the original volume and diluted with toluene (100 mL), and concentrated. The crude material was co-evaporated from toluene (3×100 mL) and dried in vacuo for 18 hours to afford the title compound as an off-white solid.
