Preparation of phosphorylated amidines |
| abstract |
Preparation of a phosphorylated amidine of the formula ##STR1## wherein X is oxygen or sulfur and R, R 1 , R 2 , R 3 and R 4 are various organic radicals, which comprises reacting a phosphoric acid ester-amide of the formula ##STR2## with a carboxamide of the formula ##STR3## at a temperature between about 0° and 50° C., and then reacting the mixture with a base. Advantageously the reaction is effected at about 0° to 15° C. in the presence of an aliphatic or aromatic optionally chlorinated hydrocarbon or an alcohol as an inert solvent, and in the presence of a catalyst. |
