Procedure

50 mmol of benzoic acid and 50 mmol of 1-hydroxybenzotriazole (HOBT) are taken in 200 ml of absolute tetrahydrofuran at 0° C. 55 mmol of dicyclohexylcarbodiimide (DCC) are added under N2 and the mixture is stirred at 0° C. for 1 hour and then at room temperature for 1 hour. 50 mmol of 5-amino-1-hydroxy-5,6,7,8-tetrahydro-naphthalene hydrobromide and 50 mmol of triethylamine are added to this solution and the mixture is stirred at room temperature for 6 hours.

Workup

  1. waitat room temperature for 1 hour
  2. stirringthe mixture is stirred at room temperature for 6 hours
