Process for producing phosphoroamidite |
摘要 |
The present invention provides high purity phosphoroamidite products by reducing the amount of impurities of triphosphite which has been additionally produced according to the conventional technique. Phosphoroamidites can be obtained with high purity such that the excess reaction is suppressed by using a reaction activator hardly generating triphosphite. According to the present invention, phosphoroamides can be obtained with high purity, which has heretofore been difficult to suppress the generation of impurities of triphosphite.
