Procedure
8-(4-methyl-1-piperazinyl)-4-oxo-4H-chromene-2-carboxylic acid hydrochloride (Reference Example 1) (400 mg, 1.23 mmol) was suspended in anhydrous N,N-dimethylformamide (20 ml) and triethylamine (0.69 ml, 4.92 mmol) was added to give a clear solution. The following were added in order: 1-hydroxybenzotriazole (HOBt (205 mg, mol)), O-(1H-Benzotriazol-1-yl)-N,N,N′,N′-pentamethylene-uronium tetrafluoroborate (TBTU (435 mg, 3.1 mmol)) then 4-(dimethylamino)pyridine (25 mg). After stirring for 5 min at room temperature, 4-(4-morpholinyl)aniline (Reference Example 21) (220 mg, mmol). The reaction stirred overnight at room temperature. The solution was concentrated in vacuo, the remains were partitioned between chloroform/saturated sodium bicarbonate, extracted (×3) with chloroform, dried (MgSO4) and concentrated in vacuo to give the crude product.
