Patent ID: 8471041

Claim:
A method of producing N-(bromoacetyl)-3,3-dinitroazetidine (ABDNAZ), comprising: reacting 1-tert-butyl-3,3-dinitroazetidine (DNAZ) with bromoacetyl bromide and boron trifluoride etherate to produce a reaction mixture comprising ABDNAZ and a salt of DNAZ; adding water and a solvent to the reaction mixture to form an organic phase comprising the ABDNAZ and an aqueous phase comprising the salt of DNAZ; separating the organic phase and the aqueous phase to produce an ABDNAZ/solvent solution comprising the ABDNAZ and the aqueous phase comprising the salt of DNAZ; adding a nonsolvent to the ABDNAZ/solvent solution to produce an ABDNAZ/solvent/nonsolvent mixture, the nonsolvent comprising an organic solvent; and recovering the ABDNAZ.
