Reaction Steps

To a mixture of methyl ({[4-amino-3-(3-methoxy-4-{[(1-methyl-1H-indol-2-yl)carbonyl]amino}phenyl)thieno[3,2-c]pyridin-7-yl]carbonyl}amino)acetate (0.130 g, 0.239 mmol) in 1,4 dioxane (10 mL) was added 2M sodium hydroxide in water (0.260 mL, 0.521 mmol). The resulting solution was heated at 50° C. for 3 hours. 1M hydrochloric acid was added until pH of the mixture was 4 and solvent was removed under reduced pressure. The resulting white solid was washed with water (2 mL) and filtered and dried to furnish the title compound (64 mg, 0.121 mmol): LCMS (Conditions b): MH+=530 RT=2.03 min; 1H NMR (DMSO-d6, 400 MHz) δ 12.65 (1H), 9.50 (1H), 8.95 (1H), 8.60 (1H), 8.02 (1H), 7.71 (2H), 7.58 (1H), 7.35 (2H), 7.21 (1H), 7.15 (1H), 7.09 (1H), 6.29 (2H), 4.04 (3H), 3.97 (2H), 3.92 (3H).
