RI - алкил с 1-3 атомами углерода, которые наход т применение в качестве гербицидов.RI is alkyl with 1 to 3 carbon atoms which find use as herbicides.

Способ основан на реакции взаимодействи  спиртов с эфирами хлоругольных кислот. Предлагаемый способ заключаетс  в том, что соответствующий 1-арил-3-алкил-5-оксигидантоин подвергают взаимодействию с эфирами хлоругольной или хлортиоугольной кислоты в среде органического растворител  в присутствии органического основани , с выделением целевого продукта ооычными приемами .The method is based on the reaction of the interaction of alcohols with chlorotic acid esters. The proposed method consists in the fact that the corresponding 1-aryl-3-alkyl-5-oxyhydantoin is reacted with chloroethyl or chlorothiol acid esters in an organic solvent medium in the presence of an organic base, with the release of the desired product by common methods.

В качестве органического основани  примен ют триметиламин, диметиланилин, пиридин и др.Trimethylamine, dimethylaniline, pyridine and others are used as the organic base.

Пример 1. К раствору 2,06 г (0,01 моль) 1-фенил-3-метил-5-оксигидантоина в 30 мл тетрагидрофурана при 20-21° С прибавл ют 1,09 г (0,01 моль) этплхлоркарбоната и по капл м 1,0 г (0,01 моль) триэтиламина. Температура реакционной смеси быстро растет до 35° С и выпадает белый осадок сол нокислого триэтиламина. Перемешивают 15- 20 мин, пока температура реакционной смеси не достигнет 20° С. Осадок отфильтровывают, Example 1. To a solution of 2.06 g (0.01 mol) of 1-phenyl-3-methyl-5-oxyhydantoin in 30 ml of tetrahydrofuran at 20-21 ° C was added 1.09 g (0.01 mol) of propyl chlorocarbonate and dropwise 1.0 g (0.01 mol) of triethylamine. The temperature of the reaction mixture quickly rises to 35 ° C and a white precipitate of triethylamine hydrochloride falls out. Stir for 15-20 minutes until the temperature of the reaction mixture reaches 20 ° C. The precipitate is filtered,

The residue crystallizes. 2.6 g (93.5% of theoretical) of 1-phenyl-3-methyl-5-oxygndantoin 0-ethyl carbonate are obtained.
