Reaction Steps

8-Butoxy-3-aminomethyl-7-methoxy-2-oxo-1,2-dihydroquinoline (56.6 mg, 0.205 mmol) obtained in Example 7-2 was dissolved in chloroform (1 ml), and 4-fluorophenyl isocyanate (25.6 μl, 0.225 mmol) was successively added thereto while being cooled with ice. The mixture was stirred at the same temperature for 30 minutes, to which methanol (30 μl) and triethylamine (30 μl) were added, and was further stirred for 30 minutes. The reaction solution was concentrated under reduced pressure, and the resultant residue was washed with toluene to give the title compound (73 mg, yield 86%) as colorless crystals (Table 31).
