Reaction Steps

A mixture of 6-(1-methanesulfonyl-1-methyl-ethyl)-8-{3-[3-(2-trimethylsilanyl-ethoxymethyl)-3H-imidazo[4,5-b]pyridin-6-yl]-phenyl}-quinoline from Step 2 (1.0 eq.), TBAF (2.0 eq.) and ethylene diamine (1.5 eq.) in DMF (0.2M) was stirred at 80° C. for 3 h. The mixture was cooled, diluted with water, filtered. The resulting solid was stirred in acetone to afford the title compound after filtration. 1H NMR (500 MHz, DMSO-d6): δ 8.94 (dd, 1H), 8.72 (s, 1H), 8.52 (dd, 1H), 8.47 (s, 1H), 8.30–8.25 (m, 2H), 8.08 (d, 1H), 7.98 (s, 1H), 7.79 (d, 1H), 7.68 (d, 1H), 7.63–7.60 (m, 2H), 2.81 (s, 3H), 1.93 (s, 6H).
