To a mixture of 3-(4-chloro-phenyl)-7-ethynyl-4-hydroxy-isothiazolo[5,4-c]pyridine-5-carboxylic acid ethyl ester (0.106 mmol) and CH2Cl2/H2O (1/1, 0.70 mL) was added benzylazide (0.117 mmol), CuSO4.5H2O (0.0053 mmol) and sodium L-ascorbate (0.0159 mmol). The mixture was stirred at rt for 16 h before it was partitioned between H2O (20 mL) and CH2Cl2 (20 mL). The aqueous phase was then extracted with CH2Cl2 (2×15 mL). The combined organic layers were washed with brine and water, dried over MgSO4 and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel, eluting with 0-20% EtOAc/CH2Cl2, to give the title compound (40 mg) as a white solid: MS (m/z) 492.1 (M+1).
