Abstract
4,6-ไดโบรโม-3-ไฮดรอกซิพิโคลิโนไนไทรล์อาจถูกเตรียมจากเฟอร์ฟูรอลในอนุกรมขั้นตอน เคมีที่ถูกเลือกจากการอะมิเนชันด้วยไซยาโน, การก่อตัวเป็นเกลือเอมีนและการโบรมิเนชัน-การจัด เตรียมใหม่ กรด 4-แอลคอกซิ-3-ไฮดรอกซิพิโคลินิคอาจถูกเตรียมตามธรรมดาจาก 4,6-ไดโบรโม-3- ไฮดรอกซิพิโคลิโนไนไทรล์ในอนุกรมขั้นตอนเคมีที่ถูกเลือกจากการแทนที่ด้วยโบรโม, การไฮโดร- ไลซิสด้วยไนไทรล์และการรีดักชันด้วยฮาโลเจน 4,6-dibromo-3-hydroxycolinonitrile may be prepared from furfural in step series Chemistry selected from cyanocyanate amine, amine salt formation and bromination - 4-lcoxin-3-hydroxyl acid reconstitution. Colinic may be normally prepared from 4,6-dibromo-3-hydroxycolinonitrile in the chemical process series selected from bromo replacement, hydrolysis with nitrile and Reduction with halogen
