Abstract
Methods for removing 1,3,5-trimethylhexahydro-1,3,5-triazine and N-methylenemethanamine from a N-methylimidazole and methods for making oligonucleotides using N-methylimidazole are provided. In one embodiment, a method for removing 1,3,5-trimethylhexahydro-1,3,5-triazine and N-methylenemethanamine from a feedstock containing N-methylimidazole includes contacting the feedstock with small or medium pore molecular sieves. The small or medium pore molecular sieves adsorb 1,3,5-trimethylhexahydro-1,3,5-triazine and N-methylenemethanamine from the feedstock. The method further includes separating the small or medium pore molecular sieves from the feedstock.
