Procedure

A solution of N-[2-[[(2,3-Difluorophenyl)methyl]thio]-6-methoxypyrimidin-4-yl]piperazine-1-sulfonamide, trifluoroacetate salt (the product of example 36, 0.6 g) in 4N HCl/dioxane (2 mL) and Et2O (20 mL) was stirred at room temperature for 20 min. The resulting suspension was filtered and the residue dried in a vacuum oven at 40° C. for 2 h to give the subtitle compound as a white solid. Yield: 0.55 g.
