Azidomethyl 2,2-dimethylpropanoate → [4-(4-(Aminocarbonyl)-5-{[6-(morpholin-4-ylmethyl)pyridin-2-yl]amino}-2-thienyl)-1H-1,2,3-triazol-1-yl]methyl pivalate

Participants

Reaction Steps

5-Ethynyl-2-{[6-(morpholin-4-ylmethyl)pyridin-2-yl]amino}thiophene-3-carboxamide (86 mg, 0.25 mmol) and azidomethyl pivalate (59 mg, 0.38 mmol) were combined in DMF (1.0 mL). CuSO4.5H2O (6.3 mg, 0.025 mmol) in water (0.2 mL) and sodium ascorbate (20 mg, 0.10 mmol) in water (0.2 mL) were added, and the reaction mixture was stirred at room temperature overnight. The reaction was concentrated to dryness, combined with MeOH and silica gel, and evaporated. Flash chromatography (dry load, 0-10% MeOH/EtOAc) afforded the title compound as a yellow solid.
