実験手順
5-(3,4-Dimethoxyphenyl)furylformaldoxime (9.5 g, 0.038 mole) and DMF (500 ml) was treated with methyl isocyanate (16 ml, 0.27 mole). The solution was stirred at room temperature for 4 hours and at steam bath temperature for 1 hour. The reaction solution was poured into 3 liters of water. The tan precipitate was collected to give 6 g (51%) of product.
