Description

3 Пример 3. К раствору 0,6 г 1-трет-бутиламино-2-фенил - 2 - акрилоиламиноэтана в 7 мл спирта добавл ют 1,1 мл 20%-.ного водного формальдегида и 0,3 г поташа, нагревают 30 мин ири 100° С, /концентрируют в вакууме досуха, экстрагируют продукт 5x50 мл эфира, сушат экстракт сульфатом , отгон ют растворитель, перегон ют остаток в вакууме и получают 0,51 г (80,5%) 1-трет-бутил-З-аКрилоил-4-феннлимидазолидина . Свойства синтезир01ванных 1-г/9ет-бутил-3ацил-4-фенилимидазолидинов приведены в та-блице.3 Example 3. To a solution of 0.6 g of 1-tert-butylamino-2-phenyl-2-acryloylaminoethane in 7 ml of alcohol is added 1.1 ml of 20% aqueous formaldehyde and 0.3 g of potash, heated for 30 minutes Irie 100 ° C, / are concentrated in vacuo to dryness, the product is extracted with 5x50 ml of ether, the extract is dried with sulphate, the solvent is distilled off, the residue is distilled in vacuum and 0.51 g (80.5%) of 1-tert-butyl-3 is obtained aCryloyl-4-phennlimidazolidine. The properties of the synthesized 1-g / 9et-butyl-3 acyl-4-phenylimidazolidines are given in the table.
