实验步骤: N-propylphthalimide (50 g) was nitrated in 500 g 99% nitric acid to produce 4-nitro-N-propylphthalimide under conditions described in Example 2.

反应条件: temp:20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 3-Hydroxy-2-propyl-2,3-dihydroisoindol-1-one is prepared as described in Example 1, starting with 1.5 g of N-propylphthalimide in 25 cm3 of methanol and 0.48 g of potassium borohydride. The reaction mixture is stirred at a temperature in the region of 20° C. for 20 hours and is then cooled to a temperature in the region of 0° C. and distilled water is added dropwise. The methanol is then partially evaporated off under reduced pressure (2 kPa) at a temperature in the region of 35° C. and the residue is cooled to 0° C. The precipitate obtained is filtered off and then washed with cold water. The solid is taken up in dichloromethane and the solvent is then evaporated to dryness under reduced pressure (2 kPa) at a temperature in the region of 35° C. 1.0 g of 3-hydroxy-2-propyl-2,3-dihydroisoindol-1-one is thus obtained in the form of a beige-colored powder. (Rf=0.6, thin layer chromatography on silica gel, eluent: cyclohexane/ethyl acetate (30/70 by volume)). 3-Hydroxy-2-propyl-2,3-dihydroisoindol-1-one is prepared is then cooled to a temperature in the region of 0° C. distilled water is added dropwise The methanol is then partially evaporated off under reduced pressure (2 kPa) at a temperature in the region of 35° C. the residue is cooled to 0° C The precipitate obtained is filtered off washed with cold water the solvent is then evaporated to dryness under reduced pressure (2 kPa) at a temperature in the region of 35° C
