Reaction Steps

30.3 mg of 6-[(4-morpholinophenyl)amino]-4-[(pyrrolidin-2-ylmethyl)amino]pyridine-3-carboxyamide (the compound of Example 358) was dissolved in 2 mL of methylene chloride, to which 9.4 mg of acetic anhydride and 9.1 mg of pyridine were sequentially added, and stirred at room temperature for 2 hours. To the reaction mixture saturated sodium bicarbonate in water was added, extracted with chloroform:methanol=10:1, 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:ammonia methanol=8:1), recrystallized from chloroform-ether to obtain the title compound (29.3 mg, 87%) as a light yellow crystalline powder.
