Versuchsvorschrift

HATU (10.3 mg) and 5-(quinolin-3-yl)-6,7,8,9-tetrahydropyrimido[5,4-b]indolizine-4,8-diamine (8.8 mg) obtained in Step 11 of Example 1 were added to a solution of trans-4-dimethylaminocrotonic acid hydrochloride (4.5 mg) in DMF (0.5 ml) at room temperature. After being stirred for 1 hour at the same temperature, the mixture was poured into a saturated aqueous sodium bicarbonate solution, followed by extraction with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and the solvent was then distilled off under reduced pressure. The resulting residue was purified by preparative thin-layer chromatography (produced by Wako, NH2 silica-gel 60 F254 plate, developing solvent: chloroform/methanol) to obtain the title compound as a light-yellow solid (6.4 mg).
