Abstract: The instant invention relates to a method of phosphorodiamidite production that comprises: (E1) preparing a purified solution of a dialkylamine in a polar solvent as follows: —the dialkylamine dissolved in a polar solvent is contacted with a quantity of phosphorus trihalide that is sufficient to react with the alcohol impurities contained in the dialkylamine but sufficiently low to leave a major part of the dialkylamine unreacted, whereby a mixture is obtained that contains the dialkylamine in the polar solvent and reaction products of the impurities with the phosphorous trihalide; —the unreacted dialkylamine and polar solvent present in the mixture obtained in step (E1.1.

Abstract: A method of phosphorodiamidite production comprising the steps of reacting a phosphorus trihalide with a dialkyl amine in a polar solvent to form an intermediate compound. This intermediate compound is then subsequently reacted with an hydroxylalkyl compound and a dialkyl amine in the presence of a non-polar cosolvent. Following filtration to remove the solid by-product the two solvents form separate layers. This is advantageous as the upper, non-polar solvent, layer contains the high-purity phosphorodiamidite product.
