How is 4-(Oxiran-2-ylmethoxy)-N,N-bis(oxiran-2-ylmethyl)aniline (CAS: 5026-74-4) typically synthesized?

4-(Oxiran-2-ylmethoxy)-N,N-bis(oxiran-2-ylmethyl)aniline can be synthesized via the reaction of diphenylamine with oxiran-2-ylmethyl chloride in the presence of a base such as triethylamine. The reaction typically yields a product with a purity of over 90%. This process involves the formation of a new amide bond and the introduction of an oxirane group, which are key steps in the synthesis.
