Versuchsvorschrift

2-(tert-butoxycarbonylamino)-5-hydroxyindan (100 mg, 0.40 mmol) synthesized in the above Reference Production Example 1 was dissolved in acetone (2 ml), to which potassium carbonate (58 mg, 0.45 mmol) and benzylbromide (48 μl, 0.40 mmol) were added, and the mixture was heated to reflux for 3 hours. The reaction mixture was extracted with ether and dried, and then the solvent was distilled off under reduced pressure to obtain 2-(tert-butoxycarbonylamino)-5-phenoxyindan (120 mg, 0.36 mmol) having the following physical properties:
