Reaction Steps

2-[5-(7-Chloro-thieno[3,2-b]pyridin-2-yl)-1-methyl-1H-imidazol-2-yl]-propan-2-ol (190 mg, 0.62 mmol) and 2-methyl-5-aminoindole (108 mg, 0.714 mmol) were dissolved in 3 mL of t-butyl alcohol and 3 mL of dichloroethane and the solution was heated to 85° C. After allowing the reaction to go dry overnight solvent was added along with an additional 45 mg of the indole an the solution was heated an additional 18 hours. Chromatography of the residue with 20% methanol:methylene chloride afforded 166 mg (66%) of 2-{1-methyl-5-[7-(2-methyl-1H-indol-5-ylamino)-thieno[3,2-b]pyridin-2-yl]-1H-imidazol-2-yl}-propan-2-ol. 1H NMR (400 MHz, CD3OD) δ8.17 (d, 1H), 7.51 (s, 1H), 7.44 (s, 1H), 7.40 (d, 1H), 7.02 (d, 1H), 6.84 (s, 1H), 6.20 (s, 1H), 3.33 (s, 3H), 2.44 (s, 3H), 1.64 (s, 6H). LC-MS: 418, 419 (MH+); HPLC RT: 3.98 min.
