실험 절차

Triethylamine (0.157 ml) and methanesulfonyl chloride (0.074 ml) were added to a solution of 4-amino-5-(quinolin-3-yl)-6,7,8,9-tetrahydropyrimido[5,4-b]indolizin-8-ol (288 mg) obtained in Step 8 in THF (5 ml) under ice-cooling. After stirring at the same temperature for 15 minutes, 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. The solvent was distilled off under reduced pressure to obtain the title compound as a light-brown solid (615 mg).
