Acetone → 3-[4-Chloro-6-(1,1,3,3-tetramethylbutylamino)-s-triazin-2-yl]-3-azabicyclo[3.2.2]nonane

Participants

Reaction Steps

Thirty grams (0.11 mole) of 3-(4,6-dichloro-s-triazin-2-yl)-3-azabicyclo[3.2.2]nonane is dissolved in 300 ml. of acetone and then 370 ml. of water is added followed by 20 g. (0.15 mole) of tert-octylamine. After stirring for 10 minutes, 4.4 g. (0.11 mole) of NaOH in 30 ml. of water is added over 20 minutes. The reaction is then heated to reflux for 19 hours. After cooling to room temperature, one liter of water is added, stirred for one hour and the white precipitate filtered off. The precipitate is washed with water, dried overnight, dissolved in dichloromethane and filtered through Magnesol®. The Magnesol® is then washed with dichloromethane, solvent removed in vacuo and recrystallized from dichloromethane-hexanes giving 20 g. of colorless crystals, m.p. 159°-162.5° C.
