実験手順
To a solution of 4 parts of 1-(2-azidoethyl)-2-methylimidazole in approximately 40 parts of 2-propanol is added 10 parts of a 20% solution of hydrogen chloride in 2-propanol. The precipitate which results (formation of which can be speeded by introducing a small amount of anhydrous ether) is isolated by filtration, washed with anhydrous ether, dried in air, and recrystallized from a mixture of 2-propanol and anhydrous ether to give 1-(2-azidoethyl)-2-methylimidazole hydrochloride melting at 132°-133.5°.
