실험 절차

To a solution of 4-carboxy-2-(4-pyridyl)thiazole (89 mg, 0.43 mmol) in anhydrous N,N-dimethylformamide (25 mL) was added 1,1'-carbonyldiimidazole (73 mg, 0.45 mmol) and the reaction was heated at 75° C. When the carbon dioxide evolution had ceased (after 30 min), the reaction was cooled to room temperature and a solution of (R)-2-amino-8-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydronaphthalene (100 mg, 0.41 mmol) in anhydrous N,N-dimethylformamide (5 mL) was added. The reaction was allowed to stir at ambient temperature for 17 h and the solvent was evaporated in vacuo. Purification on a silica gel column using chloroform/ethanol saturated with NH3 (100:3) as the eluent gave 110 mg (61% yield) of the title compound as white crystals: mp 187-188° C.; [α]21D -82° (c 1.0, chloroform); EIMS (70 eV) m/z (relative intensity) 433 (2, M+).
