실험 절차

Two moles, 540 g., of anisil (4,4'-dimethoxybenzil), 222 g. (2 moles) of semicarbazide hydrochloride, 180 g. (2.2 moles) of sodium acetate and 2.5 liters of acetic acid were refluxed overnight. The cooled reaction mixture was poured into 5 liters of water. The crude solid product was collected by filtration, washed with water and recrystallized from acetic acid. The yield was 434 g. of 3-hydroxy-5,6-bis(4-methoxyphenyl)-1,2,4-triazine, mp about 272°-274°C.
