Reaction Steps
A stirred solution of 3.57 grams of 1-methyl-2-(nitromethylene)imidazolidine (Compound 1) in 25 milliliters of water was treated dropwise with 3.99 grams of bromine at room temperature. After 30 minutes, the reaction mixture was extracted with methylene chloride. The extract was dried (MgSO4) and the solvent was evaporated to give 3.0 grams of crude product, melting point 100° (with vigorous decomposition). Recrystallization of the crude product from methylene chloride gave 15, melting point: 97° (explodes).
