Hydrazine hydrate (1:1) → HCID 178419935, compound

Participants

Reaction Steps

To a solution of 0.61 g of (2-chlorothiophen-3-yl)-(naphthalen-2-yl)-methanone in 6 mL of ethanol was added 0.12 mL of hydrazine monohydrate at room temperature and heated under reflux for 2 days. The reaction solution was diluted with ethyl acetate, and the organic layer washed successively with saturated aqueous ammonium chloride and saturated brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated. The resultant crude product was purified and separated by silica gel column chromatography (ethyl acetate:n-hexane=1:30-1:5), to afford 32 mg of the title compound as colorless crystals.
