실험 절차

(S)-N-[5-(4-Methylpiperazin-1-yl)-3,4-dihydro-2H-1-benzopyran-3-yl]-4-[4-(2-benzyloxyethyl)-piperazin-1-yl]benzamide (150 mg, 0.27 mmol) was dissolved in acetic acid (10 mL) and palladium (10%) on carbon (12 mg) was added. Hydrogenation at room temperature and at atmospheric pressure for 14 h followed by filtration and evaporation of the solvent in vacuo gave 180 mg of a crude product. The residue was partitioned between methylene chloride (60 mL) and 2 M NH3 (5 mL) and washed with brine (5 mL). Drying (MgSO4) the solution and evaporation of the solvent in vacuo gave 120 mg of crude material. Purification by preparative TLC on silica using chloroform/methanol/concentrated ammonia 95:5:0.5 as the eluent afforded 37 mg (29% yield) of the title compound as a white solid: mp 211-212° C.; EIMS (70 eV) m/z (relative intensity) 479 (8, M30 ); [α]22D−26° (c 0.26, chloroform).
