The second step is removal of the ...The first step in DNA synthesis is to attach a protected deoxynucleoside to a silica (SiO 2 ) support by an ester linkage to the 3′ –OH group of the deoxynucleoside. The second step is removal of the DMT protecting group by treatment with dichloroacetic acid in CH 2 Cl 2 . The reaction occurs by an S N 1 mechanism and proceeds rapidly because of the stability of the tertiary, benzylic dimethoxytrityl cation.

After the oligonucleotide chain of the desired sequence has been made, the final step is the removal of all the protecting groups and the linkage to silica by reaction with aqueous ammonia (NH 3 ).
