Tributylvinyltin → 3-Ethenyl-1-methyl-1h-indazole

Participants

Reaction Steps

A solution of compound 1 (1.6 g, 8 mmol) and vinyl tributyl tin (2.6 mL, 11 mmol) in toluene (10 mL) was treated with Pd(PPh3)4 (0.92 g, 0.8 mmol) and heated to reflux overnight. The reaction mixture was concentrated and the resulting material was purified directly by gradient elution on silica gel (0 to 20% EtOAc in hexanes) to afford the title compound as a colorless oil.
