Route of Synthesis (ROS)
| Conditions | Yield |
| With N-ethyl-N,N-diisopropylamine In acetonitrile at 0 – 25℃; for 17h; Experimental Procedure 1 Synthesis of Carbamoyl AICA EXAMPLE 1 Synthesis of Carbamoyl AICA 200 g of base AICA as is (K. F. 11 %) corresponding to 178 g of 100% base AICA and 1000 ml of acetonitrile are charged in a 2-liter reactor. The mixture is stirred at room temperature (about 20° C.) and 267 g of N-Succinimidyl-N’-methyl carbamate and 191.7 g of diisopropylethylamine (DIPEA) are added to the suspension. The temperature of the mixture is kept at 25+2° C. for 16 hours, then the mixture is cooled at 0÷5° C., held for an hour and the suspension is filtered on a Buchner, by washing with 2*200 ml of deionised water. 313.0 g of wet product are discharged, which is then dried on a rotavapor for 5 hours at 50° C. with vacuum line. 212 g of Carbamoyl AICA (96.9% HPLC purity) are obtained, with 0.13% K. F. 88% yield. | 88% |
