A solution of 2-{3-Phenyl-4-[(pyridin-2-ylmethyl)-amino]-thieno[2,3-b]pyridin-6-yl}-malonic acid diethyl ester (87 mg, 0.18 mmol) in dry THF (10 ml) was cooled to 0° C. under nitrogen. Diisobutyl Aluminium Hydride (1.46 ml of a 1M solution in hexanes, 1.46 mmol) was added dropwise over 2 min and the mixture stirred at 0° C. for 1 h, then allowed to reach room temperature overnight. The reaction was quenched at 0° C. by adition of 1M Rochelle's salt (10 ml). The mixture was extracted with DCM (3×20 ml), the extracts combined, washed with brine (50 ml), dried over magnesium sulphate and concentrated. The residue was purified on silica, eluting (Ethyl Acetate, 100%) to give 2-{3-Phenyl-4-[(pyridin-2-ylmethyl)-amino]-thieno[2,3-b]pyridin-6-yl}-propane-1,3-diol as a yellow oil. Yield=22.5 mg, (31.4%).
