Participants

Reaction Steps

39 g (0.06 mole) of tetrabutylammonium hydroxide solution (40% in water) is added to the suspension of 13.15 g of N-(2,6-dimethylphenyl)-maleamic acid in 100 ml of methanol, and the reaction mixture is stirred for one hour at room temperature. The pH-value is adjusted to about 7.0 with acetic acid, and the solvent is removed in vacuo in a rotary evaporator to leave 30.8 g of N-(2,6-dimethylphenyl)-maleamic acid tetrabutylammonium salt in the form of yellow oil, which crystallises on prolonged standing.
