Reaction Conditions:
with nitric acid in water at 20; for 0.25 h;
Steps:
1
It was mixed in a round-bottom flask piperonal (7) (6,66 mmol; 1g) and 3,3 ml_ of concentrated HNO3, remaining the result suspension in r.t. under vigorous magnetic agitation. It is observed immediate change of color (colorless to yellow). TLC reveals the end of reaction in 15 minutes. The isolation is performed through ice-bath cooling of reactional medium, observing immediate precipitation. The yellow solid precipitated is filtrate in bckner funnel and washed with NaHCO3 solution saturated, followed by washing with distilled water until the pH=7.
