Procedure

N-(5-{2-bromo-5-[(3-hydroxypiperidin-1-yl)sulfonyl]-3-thienyl}-4-methyl-1,3-thiazol-2-yl)acetamide obtained in Step I as described above (54 mg; 0.112 mmol; 1 eq), is dissolved in dry TBF (5 ml) at −70° C. under an inert atmosphere. n-Butyllithium (0.15 ml; 1.6 M; 0.24 mmol; 2.20 eq) is added slowly and reaction stirred at −70° C. for 1 hour before being hydrolyzed with water (0.3 ml). Reaction is warmed up to room temperature before being concentrated to dryness. Residue is taken up with water (2 ml) and EtOAc (10 ml). The organic phases are decanted, dried over MgSO4, filtrated and evaporated. Title compound is purified by reverse preparative HPLC, affording expected Compound (48) as a white solid (20 mg; 43%).
