Reaction Steps

To a solution of 4-(4-{2-[bis-(4-methoxy-benzyl)-amino]-pyrimidin-5-yl}-2-morpholin-4-yl-5,6-dihydro-pyrrolo[2,3-d]pyrimidin-7-yl)-benzoic acid (30 mg, 0.0468 mmol) obtained in Example 1-D-09 in dimethylformamide (1 ml), Hunig's base (41 μl, 0.234 mmol), HOBt monohydrate (8.3 mg, 0.0468 mmol), WSC hydrochloride (17.6 mg, 0.0702 mmol) and ammonium chloride (5.0 mg, 0.0936 mmol) were added, followed by stirring at 80° C. for 3 hours. To this, water (5 ml) was added, and the solid was filtered off. To this, trifluoroacetic acid (1 ml) and concentrated sulfuric acid (2 drops) were added, followed by stirring at 40° C. for 3 hours. After concentration of TFA under reduced pressure, water was added, followed by neutralization with 1M aqueous sodium hydroxide solution. The solid was filtered, and subsequently suspended in dichloromethane/hexane=9/1, which was stirred at room temperature for 30 minutes, followed by filtering the solid, to obtain the desired compound.
