Procedure

5-Ethynyl-2-{[6-(morpholin-4-ylmethyl)pyridin-2-yl]amino}thiophene-3-carboxamide (Example 599, Step 4) (75 mg, 0.22 mmol) and trimethylsilylmethyl azide (0.65 ml, 0.44 mmol) were combined in DMF (1.0 mL). CuSO4.5H2O (5.5 mg, 0.022 mmol) in water (0.2 mL) and sodium ascorbate (17 mg, 0.088 mmol) in water (0.2 ml) were added, and the reaction mixture was stirred at room temperature overnight. The reaction was evaporated to dryness, combined with MeOH and silica gel, and evaporated. Flash chromatography (dry load, 0-10% MeOH/EtOAc) afforded the title compound a yellow solid.
