실험 절차

Into a two liter flask, provided with a cooling device, were introduced successively a solution of methanolic potash (100 g of KOH and 500 cm3 of methanol), then 100 g (0.46 mole) of 4,5-dimethoxy 2-nitro chlorobenzene and carborundum. The mixture was brought to boiling under reflux for 6 h. After cooling, the reaction medium was filtered; the precipitate obtained was washed with methanol.
