Procedure

To a stirred solution of 1-(4-methylpiperazin-1-yl)naphthalene-7-carboxylic acid (0.270 g, 1.00 mmol) in anhydrous tetrahydrofuran (5 mL) at room temperature was added carbonyl diimidazole (0.178 mg, 1.10 mmol, 1.1 eq) directly as a solid. The resulting reaction solution was stirred at room temperature under nitrogen for 3 hours. The appropriate amine (1.1 mmol, 1.1 eq) was then added, and the resulting reaction solution was stirred at room temperature under nitrogen for 16 hours. A saturated solution of sodium hydrogen carbonate was added, and the resulting aqueous mixture was extracted with ethyl acetate (2×25 mL). The organic extracts were combined, dried (MgSO4), and evaporated under reduced pressure. Column chromatography of the residue using silica gel (approximately 50 g) and an appropriate solvent system afforded the corresponding 1-(4-methylpiperazin-1-yl)naphthalene-7-carboxamide.
