исобенность предлагаемого способа лл1чЛВ )чаетс в том, что взамен блочна) (1ты, употреол емой R известном ciiocunc получении изоцитозииа, нримен ют болус дешевую и доступную р-хлор .молочную 1;ислоту.The feature of the proposed method is hl1 hlv) that instead of block) (1 t, used for R known ciiocunc to obtain isocytosis, use a cheap and available p-chloro milk 1; bol).
Пример. В 30 мд. 20%-ноги олеума нри темпе)атуре минус 2° и хорошем перемешивании добавл ют последовательно (,2 I. Р-хло1)молочно 1 кислоты и 15,7 г. с(риок11слого гуанидина. Затем реакционнуи массу медленно нагревают до 120° и выдерживают HJJH ;-ITOH температуре 20 iiHii.Example. In 30 ppm 20% of oleum legs at a tempo of minus 2 ° and good stirring are added successively (, 2 I. P-chlor1) lactic acid 1 and 15.7 g. maintain HJJH; -ITOH temperature 20 iiHii.
