Participants

Reaction Steps

To a stirring solution of psoromic acid (1 mmol) in ethanol (25 mL) was added hydrazine hydrate (1 mmol). The reaction was stirred for half an hour and monitored by TLC. Upon completion, all of the solvent was removed by rotary evaporation. The residue was redissolved in ethanol and dried over anhydrous magnesium sulfate, filtered, and evaporated by a rotary evaporator to yield a white solid product.
