Ethylenediamine → 3-(Nitromethyl)-1,2-dihydronaphthalene

Participants

Reaction Steps

A solution of β-tetralone (Aldrich Chemical Co., Milwaukee, Wis. 53233) (24.5 gm) and ethylenediamine (1.75 gm) in nitromethane (250 ml) was heated at 80° for 16 hours. The reaction mixture was filtered, and the filtrate was evaporated to give a red oil. This was partially purified by elution through a short silica column, eluting with hexane/EtOAc (9:1 v/v). The product was a pink oil (26 gm) which was not purified further but was taken directly for the next reaction.
