A 4N hydrogen chloride ethylacetate solution (1 ml) was added to an ethyl acetate solution (2 ml) of 5-fluoro-3-(4-methoxyphenyl)-4-oxo-8-propoxy-4H-quinolin-1-ylmethyl (tert-butoxycarbonylmethylamino)acetate (100 mg, 0.19 mmol) and stirred at room temperature for 3 hours. The deposited insoluble matter was collected by filtration, washed with acetone, and then dried, giving a white powder of 5-fluoro-3-(4-methoxyphenyl)-4-oxo-8-propoxy-4H-quinolin-1-ylmethyl methylaminoacetate hydrochloride (78.3 mg, yield: 88%).
