実験手順

A mixture of tert-butyl 2-nitrobenzoate (2.1 g.) in methanol (200 ml.) was hydrogenated over palladium-carbon (2 g.) with shaking at atmospheric pressure and room temperature for 3.5 hours. The reaction mixture was filtered to remove the catalyst and then evaporated. To the residue were successively added diethyl ether and an aqueous solution of sodium chloride followed by shaking. The organic layer was separated, dried over magnesium sulfate, treated with activated charcoal and then evaporated to give an oil of the title compound (16.13 g.).
