Procedure
A mixture of (6-chloro-3-phenyl-thieno[2,3-b]pyridin-4-yl)-pyridin-2-ylmethyl-amine (20 mg, 0.57 mmol) and ethanolamine (1 ml) were heated to 200° C. in the microwave and maintained at this temperature for 90 min. On cooling, the reaction mixture was poured into DCM (50 ml) and washed with water (2×50 ml), dried (Na2SO4), and concentrated. The residue was purified on silica (ethyl acetate, 100%) to give 2-{3-phenyl-4-[(pyridin-2-ylmethyl)-amino]-thieno[2,3-b]pyridin-6-ylamino}-ethanol as a white solid. Yield=18 mg (83.9%).
