Participants

Reaction Steps

(+)-1,2-trans-Diaminocyclohexane (250 mg, 2.18 mmol) in CH2Cl2 (20 mL) was treated with Na2SO4 (923 mg, 6.50 mmol) and trimethylacetaldehyde (473 μL, 4.35 mmol). The mixture was stirred at ambient temperature under an atmosphere of N2 for 0.5 h then filtered. The filter was washed with CH2Cl2 (5 mL) and the combined organics were evaporated to give N,N′-bis-(2,2-dimethylpropylidene)-cyclohexane-1,2-diamine (610 mg, 98%) as an off-white semi solid.
