Reaction Steps

A solution of carbamate (a) (0.95 g) in dichloromethane/trifluoroacetic acid (20 ml/20 ml) was stirred for 1 hour then evaporated to dryness, azeotroping with toluene and chloroform. The residue was dissolved in water and extracted with ethyl acetate. The aqueous extract was basified with solid potassium carbonate and evaporated. The residue stirred with 10% methanol in chloroform. Filtration and evaporation afforded an oil (0.7 g).
