{3-Phenyl-4-[(pyridin-2-ylmethyl)-amino]-thieno[2,3-b]pyridin-6-yl}-acetic acid ethyl ester (47 mg, 0.12 mmol) was dissolved in dry THF (10 ml) under nitrogen and cooled to 0° C. Diisobutyl Aluminium Hydride (0.466 ml of a 1M solution in hexanes, 0.466 mmol) was added dropwise over 2 min and the mixture stirred at 0° C. for 1 h, then stirred at room temperature overnight. The reaction was cooled to OC and water (5 ml) was added carefully, followed by 1M Rochelle's salt (5 ml). The reaction was stirred at room temperature for 15 min, and then extracted with DCM (2×25 ml), the extracts combined, dried over magnesium sulphate, and concentrated. The residue was purified on silica, eluting (Ethyl Acetate/Petroleum ether), 50-100%) to give 2-{3-Phenyl-4-[(pyridin-2-ylmethyl)-amino]-thieno[2,3-b]pyridin-6-yl}-ethanol as a brown solid. Yield=25.3 mg (60.4%).
