Procedure

In a sealed reactor, 4.32 g (30 mmol, 1 eq) of 2-naphthol, 2.85 g (30 mmol, 1 eq) of (NH4)2SO3 and 50 mL of aqueous ammonia were mixed. The mixture was heated to 150° C., the pressure was raised to 10 bars and the mixture was stirred overnight. The mixture was then cooled down to room temperature.

Workup

  1. temperaturethe pressure was raised to 10 bars
  2. temperatureThe mixture was then cooled down to room temperature
