Procedure

Hydrogenate 3.0 g of 2-(2,4-dinitrobenzylidene)-1-methylpyrrolidine in 50 ml of ethanol with platinum/hydrogen. Filter the catalyst from the hydrogenated product and concentrate the filtrate to obtain the title compound as a yellowish viscous oil which decomposes rapidly in contact with air and under light.

Workup

  1. filtrationFilter the catalyst from the hydrogenated product
  2. concentrationconcentrate the filtrate
