Reaction Steps

To a solution of 4-[4-(4-Methanesulfonyl-phenoxymethyl)-thiazol-2-yl]-piperazine-1-carboxylic acid tert-butyl ester (Example 91, 430 mg, 0.95 mmol) in methanol (5 mL) was added 4 N HCl in dioxane (5 mL). The resulting solution was stirred for 30 minutes at room temperature. The mixture was then evaporated to dryness in vacuo to afford the desired product as a pale yellow solid.
