Reaction Steps

A solution of 6-methoxy-8-(4-methyl-[1,4]diazepan-1-yl)-4-(2-trimethylsilanyl-ethoxymethoxy)-quinoline-2-carboxylic acid (4-morpholin4-yl-phenyl)-amide (Reference Example 27d) (0.989 g, 1.59 mmol) in 20 mL methanol was poured into 300 mL 0.05 N hydrochloric acid. The clear dark yellow solution became cloudy within 5 minutes. The mixture was stirred at room temperature for 45 minutes and then adjusted to pH 7 with 10% sodium hydroxide. The resulting yellow precipitate was isolated by filtration, washed with water, and dried under high vacuum to afford the desired product as a yellow solid (0.629 g, 80%). 1H NMR (300 MHz, DMSO, d6) δ 9.97 (bs, 1 H, C(O)NH), 7.67 (d, 2 H, Jo=8.8 Hz, ArH2′ & H6′), 7.47 (bs, 1 H, ArH5), 7.00 (s, 1 H, C═CH), 6.99 (d, 2 H, Jo=8.8 Hz, ArH3′ & H5′), 6.71 (bs, 1 H, ArH7), 3.85 (s, 3 H, OCH3), 3.75 (t, 4 H, J=4.6 Hz, OCH2CH2N), 3.70 (bs, 2 H, ArNCH2CH2CH2NCH3), 3.55 (bs, 2 H, ArNCH2CH2NCH3), 3.09 (t, 4 H, J=4.6 Hz, OCH2CH2N), 2.95 (bs, 2 H, ArNCH2CH2NCH3), 2.73 (bs, 2 H, ArNCH2CH2CH2NCH3), 2.36 (s, 3 H, NCH3), 2.07 (bs, 2 H ArNCH2CH2CH2NCH3); Mass Spec.: calc. for [C27H33N5O4+H]+ Theor. m/z=492; Obs.=492. Analysis for C27H33N5O4. 1.0 eq HCl. 0.3 eq H2O: Calculated C 60.79 H 6.54 N 13.13. Found C 60.82 H 6.53 N 13.17.
