실험 절차

4-(Morpholinocarbonyl)benzoic acid (100 mg, 0.43 mmol; described in: J. Med. Chem. 1994, 37(26), 4538-4554) and 1,1′-carbonyldiimidazole (76 mg, 0.47 mmol) were dissolved in N,N-dimethylformamide (3 mL) and heated to 75° C. for 3.5 h. Additional 1,1′-carbonyldiimidazole (36 mg, 0.22 mol) was added and the solution was stirred for 30 min. (S)-3-Amino-5-(4-methylpiperazin-1-yl)-3,4 dihydropyran-2H-1-benzopyran (100 mg, 0.40 mmol), dissolved in N,N-dimethylformamide (2 mL), was added and the reaction mixture was stirred for 18 h at 50° C. The solvent was evaporated and the residue was partitioned between ethyl acetate (30 mL) and water (5 mL). The organic layer was washed with water (5 mL) and brine (5 mL) and dried (MgSO4). The solvent was evaporated in vacuo giving 180 mg of a crude product. Purification by preparative TLC twice using chloroform/methanol/concentrated ammonia 95:5:0.5 and chloroform/ethanol (saturated with NH3) 12:1 as the eluents afforded 98 mg (53% yield) of the title compound as a white solid: mp 222° C. (decomposes); EIMS (70 eV) m/z (relative intensity) 464 (68, M+); [α]22D−1220 (c 0.44, chloroform).
