実験手順
To a solution of tert-butyl 4-(5-benzyl-4-methylpyrimidin-2-yl)piperazine-1-carboxylate (250 mg, 0.68 mmol) in dioxane (2 mL) was added 4 M HCl-dioxane (2 mL). The reaction mixture was stirred at RT for 2 h and then concentrated to afford crude 5-benzyl-4-methyl-2-(piperazin-1-yl)pyrimidine. MS (ES+) C16H20N4 requires: 268, found: 269 [M+H]+.
