A process for the production of oligonucleotides such as DNA is disclosed which comprises the phosphite triester method on inorganic solid support in which a hindered dialkylamino nucleoside phosphite having a total of 4 to 6 carbon atoms in the dialkyl group is employed as an intermediate reagent in the synthesis. The solid support preferably is controlled pore glass with a long spacer.
