Reaction Steps

22 mg of 4-[(3-aminobenzyl)amino]-6-[(4-morpholinophenyl)amino]pyridine-3-carboxyamide (the compound of Example 103) was dissolved in 0.5 mL of pyridine, to which 5.4 mg of acetic anhydride was added, and stirred at room temperature for 4 hours. To the reaction mixture, water was added, stirred, and the solvent was evaporated. The residue was purified by silica gel thin layer chromatography (chloroform: methanol=10:1) to obtain 2.6 mg (11%) of 4-{[3-(acetylamino)benzyl]amino}-6-[(4-morpholinophenyl)amino]pyridine-3-carboxyamide (Example 104-1) as a white solid. Furthermore, 11.6 mg (44%) of 4-{[3-(acetylamino)benzyl]amino}-6-[acetyl(4-morpholinophenyl)amino]pyridine-3-carboxyamide (Example 104-2) was obtained as a yellowish brown oil.
