실험 절차

6-Methoxy-8-(4-Methyl-piperazin-1-yl)-4-oxo-4H-chromene-2-carboxylic acid hydrochloride (Reference Example 2) (3.0 g, 8.5 mmol), TBTU (5.5 g, 17 mmol), 1-hydroxybenzothiazole (2.6 g, 17 mmol), 4-dimethylaminopyridine (0.05 g, catalytic) and commercially available 4-morpholin-4-yl-aniline (1.66 g, 9.3 mmol) were dissolved in dimethylformamide (100 mL). Triethylamine (3.5 mL, 25 mmol was added and this mixture stirred at room temperature for 17 hours. The reaction mixture was concentrated under vacuum and the residue was partitioned between chloroform (400 mL) and saturated aqueous sodium bicarbonate (50 mL). The organic layer was separated, dried (Na2SO4), vacuum-filtered and concentrated under vacuum. The residue was purified by chromatography on silica eluted with 2–5% methanol in chloroform and then triturated with ether to yield a yellow powder. (1.6 g=39%) LCMS−m/z=479.5 mp=234–236° C.
