実験手順

To a solution of ethyl 2-(3,4,5-trimethoxyphenyl)isonicotinate (3.17 g) in ethanol (40 mL) was added 10% potassium hydroxide (2.42 g). The mixture was stirred at room temperature for 5 hours and evaporated. Water was added to the residue and pH was adjusted to 7. White precipitates of the title compound were collected by filtration and the compound was used for next step without further purification.
