A 4.0 M solution of hydrochloric acid (117 μL, 467 μmol) in dioxane was added to a solution of 2-methyl-propane-2-sulfinic acid (3-thiazol-2-yl-oxetan-3-yl)-amide (Example 281a) (81 mg, 311 μmol) in methanol (0.5 mL) at 0° C. The mixture was stirred at 0° C. for 5 min before the solvents were removed under reduced pressure. The resulting white solid was triturated with diethyl ether and filtered off. The solid was further washed with diethyl ether and dried under high vacuum to yield the title compound (42 mg, 70%) as a white solid. MS (EI): m/e=157.1 [M+H]+.
