Procedure

To a solution of 2-methyl-propane-2-sulfinic acid [(S)-1-(2-methanesulfonyl-pyridin-4-yl)-ethyl]amide (29.9 g, 98.2 mmol) in methanol (160 mL) was added a solution of 4 N HCl in dioxane (25.8 mL, 103 mmol). After 1 hour, the solution was concentrated to half the original volume and diluted with toluene (100 mL), and concentrated. The crude material was diluted with toluene (3×100 mL) and concentrated in vacuo and dried in vacuo for 18 hours to afford the title compound as an off-white solid which was used without further purification.
