5-Bromo-6-nitroindane → HCID 20296560, compound

Participants

Reaction Steps

4.8 g. of 5-bromo-6-nitroindan, 4.5 g. of potassium tert.-butylate, 4.4 g. of 2-pyridinethiol are heated in 50 ml. of absolute dimethylformamide for 3 hours under nitrogen to 80°. The mixture is concentrated under vacuum; the residue is combined with ethyl acetate and extracted four times with water. The ethyl acetate phase is concentrated, and the residue is purified on a silica gel column (system: cyclohexane/ethyl acetate 4:1). After crystallization from ethanol, 3.3 g. of 5-nitro-6-(2-pyridylthio)indan is obtained, m.p. 74°.
