실험 절차

N-(3,4-Dichlorophenyl)piperazine-1-carboxamide hydrochloride (467 mg) and 4-(tert-butoxycarbonyl)morpholine-2-carboxylic acid (347 mg) were dissolved in dry THF (10 mL) followed by addition of N,N-diisopropylethylamine (0.52 ml) and HATU (628 mg) and the reaction was stirred for 4 h. The solvent was evaporated under reduced pressure then redissolved in ethyl acetate (50 ml) followed by washing with sat. aqueous NaHCO3 (20 ml), 10% w/v citric acid (aq.) (15 ml) and brine (15 ml). The organic layer was dried (MgSO4), filtered and evaporated. Purification by chromatography (1:1 EtOAc:hexanes 1:1 to EtOAc neat) afforded the title compound (900 mg) as an impure foam contaminated with N,N,N′,N′-tetramethylurea. The product was used without further purification.
