Reaction Steps

10 mg of 6-[(4-aminophenyl)amino]-4-(benzylamino) pyridine-3-carboxyamide (the compound of Example 65) was dissolved in 0.5 mL of methylene chloride and 0.2 mL of tetrahydrofuran, to which 33 mg of triethylamine and 41 mg of N,N-diethylcarbamoyl chloride were added, and stirred at room temperature for 3 days. To the reaction mixture, water was added, extracted with chloroform, the extract was washed with saturated saline, and dried on anhydrous sodium sulfate. The solvent was evaporated, and the residue was purified by silica gel thin layer chromatography (chloroform:methanol=5:1, developed twice) to obtain 9 mg (69%) of the title compound as a light brown crystalline powder.
