Reaction Steps

To a solution of methyl 2-(benzo[b]thiophen-2-yl)-2-methoxyacetate (0.174 g, 0.74 mmol) in absolute ethanol (3 mL) was added hydrazine hydrate (0.14 mL, 2.87 mmol) and the mixture was heated at 50° C. for 20 hours. After cooling to room temperature, the solution was concentrated in vacuo. The residue was dissolved in EtOAc and washed with water and brine, dried over Na2SO4 and concentrated in vacuo to give 2-(benzo[b]thiophen-2-yl)-2-methoxyacetohydrazide as a colorless oil (0.182 g, quantitative yield).
