Reaction Steps

A mixture of N-(1-ethylpyrazol-4-yl)-2-[4-(7-methoxy-6-methoxycarbonylquinolin-4-yloxy)phenyl]acetamide (0.05 g), lithium hydroxide (0.01 g) and methanol (1 ml) was stirred at ambient temperature for 14 hours. The resultant mixture was acidified to pH2 by the addition of 2N aqueous hydrochloric acid. The precipitate was isolated, washed with water and with diethyl ether and dried under vacuum. There was thus obtained the title compound (0.028 g); 1H NMR: (DMSOd6) 1.32 (t, 3H), 3.63 (s, 2H), 3.97 (s, 3H), 4.03-4.11 (m, 2H), 6.48 (d, 1H), 7.27 (d, 2H), 7.42 (s, 1H), 7.46 (d, 2H), 7.5 (s, 1H), 7.9 (s, 1H), 8.54 (s, 1H), 6.67 (d, 1H), 10.21 (s, 1H); Mass Spectrum: M+H+ 447.
