실험 절차

4-N-Boc-morpholine-3-acetic acid (500 mg, 2.04 mmol) and benzyl homopiperazine (388 mg, 2.04 mmol) were dissolved in DMF (20 mL) and cooled to 0° C. DIPEA (553 mg, 4.28 mmol) and HBTU (773 mg, 2.04 mmol) were added and the reaction mixture was stirred for 2 h. The solvents were removed in vacuo and the residue was partitioned between DCM (100 mL) and water (50 mL). The organic fraction was washed with 1 M aq Na2CO3 (25 mL), brine (25 mL), dried (MgSO4) and concentrated in vacuo. The residue was purified by reverse phase column chromatography to give the title compound (730 mg, 86%) as a light yellow gum. LCMS (ES+): 418.4 [MH]+.
