Procedure

To a solution of N-{2-[4-(2-hydroxyethyl)phenyl]-5-(4-methoxybenzyl)-4-oxo-4,5-dihydro-2H-pyrazolo[4,3-c]quinolin-3-yl}acetamide (3.2 g) and triethylamine (1.85 ml) in tetrahydrofuran (400 ml) was added dropwise methanesulfonyl chloride (0.77 ml) at 0° C. The mixture was stirred at room temperature for 5 hours, triethylamine (0.46 ml) and methanesulfonyl chloride (0.19 ml) were added thereto, and stirred again for 3 hours. The mixture was concentrated under reduced pressure, and to the residue was added ethyl acetate, washed with an aqueous sodium hydrogen carbonate solution, water, saturated brine, dried and concentrated under reduced pressure to obtain the target compound (3.5 g).
