Reaction Steps

To 1-{[(4aR*,6R*,8aR*)-2-amino-3-cyano-8-methyl-4H,4aH,5H,6H,7H,8H, 8aH,9H-thieno[3,2-g]quinolin-6-yl]carbonyl}-3-[2-(dimethylamino)ethyl]-1-propylurea (example 1-15) (100 mg) was added acetic acid (2 mL) and the mixture was heated at 135° C. and refluxed for 12 hours. After cooling to room temperature, the reaction mixture was concentrated under reduced pressure. To the residue were added ethyl acetate and a saturated aqueous solution of sodium bicarbonate. After the separated organic layer was dried over anhydrous sodium sulfate, it was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: 0%-5% methanol/ethyl acetate, gradient elution) to give the title compound (26 mg). The structure was illustrated in Table 11.
