Reaction Steps

To a solution of tert-butyl 4-(5-(2-fluorophenylthio)pyrimidin-2-yl)piperazine-1-carboxylate (5 g, 12.8 mmol) in dioxane (150 mL) was added HCl in dioxane (4 M, ca. 30 mL), and the mixture was stirred at 40° C. overnight. LCMS showed the reaction was completed. The reaction mixture was concentrated to afford 5-(2-fluorophenylthio)-2-(piperazin-1-yl)pyrimidine HCl salt (3.6 g, 88%) as a solid. MS (ES+) C14H15FN4S requires: 290. found: 291 [M+H]+.
