Procedure

2-Acetamido-2-[3-(4-nitrophenyl)propyl]-1,3-propanediol (400 mg) was dissolved in 50 ml of methanol and 6.7 ml of a 1 N aqueous sodium hydroxide solution was added thereto. The mixture was refluxed under heating for 3 hours and neutralized with dilute hydrochloric acid. The solvent was distilled away and chloroform was added to the residue for extraction. The chloroform layer was washed and dried, and the solvent was distilled away. The residue was purified by silica gel column chromatography (methanol:chloroform=1:4) to give 100 mg of 2-amino-2-[3-(4-nitrophenyl)propyl]-1,3-propanediol as a red, oily substance.
