실험 절차
A solution of crude 4-morpholin-4-yl-benzene-1,2-diamine (0.75 g, 3.9 mmol) in tetrahydrofuran (4 mL) was treated dropwise with a solution of carbonyldiimidazole (0.76 g, 4.7 mmol) in tetrahydrofuran (12 mL). The reaction mixture was stirred for 16 h at room temperature, and the solid product was collected by filtration and recrystallized from ethanol to afford the white solid product (0.47 g, 55%). See, J. Am. Chem., Soc., 118:4018 (1996).
