N-[5-(5-{[(2,2-dimethyl-1,3-dioxolan-4-yl)methyl]aminosulfonyl}-2-thienyl)-4-methyl-1,3-thiazol-2-yl]acetamide (14) (48 mg; 0.11 mmol; 1 eq), is dissolved in DCM (5 ml). Trifluoroacetic acid (0.2 ml) is added and reaction mixture stirred at room temperature for 30 minutes. The solvents are evaporated and the crude product purified directly by preparative HPLC, affording Compound (17) as a white-off solid (7 mg; 16%). M− (ESI): 390.2; M+ (ESI): 392.2. HPLC (method A), Rt: 2.13 min (purity: 83.5%).
