Procedure

2-Hydroxy-3-methoxybenzaldehyde-2-benzenesulfonate (50 g, 171 mM) is added to nitric acid (500 ml) at 0° C.-5° C. The solution is kept five minutes at 5° C. and then poured into ice-water (1.5 L). The crude product, a tan solid, is filtered, washed with cold water, alcohol, and then recrystallized from acetic acid (650 ml) to afford the product as a white solid; yield 30.3 g (52.6%); m.p. 152°-154° C.

Workup

  1. filtrationThe crude product, a tan solid, is filtered
  2. washwashed with cold water, alcohol
  3. customrecrystallized from acetic acid (650 ml)
