Description
Изобретение относитс к области получени соединений, которые могут найти применение в качестве фунгицидов.The invention relates to the field of the preparation of compounds which can be used as fungicides.
Предлагаемый способ получени (2пиридил ) - (2-пиридил) -N-фенилтиомочевин заключаетс во взаимодействии (2пиридил )этил аминопиридинов с фенилизотиоцианатами в присутствии триэтиламина при 80-120°С в среде органического растворител , например бензола.The proposed method for preparing (2pyridyl) - (2-pyridyl) -N-phenylthiourea involves reacting (2pyridyl) ethyl aminopyridines with phenylisothiocyanates in the presence of triethylamine at 80-120 ° C in an organic solvent, such as benzene.
Пример. Смесь 0,6 г моль фенилизотиоцианата , 0,5 г-моль N- p-{2-пиридил) этил -ааминопиридина и 0,4 г триэтиламина в 200 мл бензола нагревают (80°С) в течение 8-10 час. Затем из реакционной массы унариванием в вакууме удал ют растворитель. Оставшуюс часть обрабатывают 4-5-кратным количеством н-гексана или петролейного эфира и выдел ют нерастворимый продукт.Example. A mixture of 0.6 g mol of phenyl isothiocyanate, 0.5 g mol of N-p- {2-pyridyl) ethyl-aminopyridine and 0.4 g of triethylamine in 200 ml of benzene is heated (80 ° C) for 8-10 hours. Then the solvent is removed from the reaction mass by vacuum infusion. The remainder is treated with a 4-5 fold amount of n-hexane or petroleum ether and the insoluble product is isolated.
