Reaction Steps
The procedure of Example 1 is repeated using 3.0 g (19 mmol) of 1-oxyl-2,2,6,6-tetramethyl-4-hydroxypiperidine, 4.64 g (45 mmol) of tert-butyl nitrite, 11.45 mg (0.019 mmol) of (S,S)-(+)-N,N-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminocobalt(II) mmol) in 80 mL of pyridine and 6.27 g (38 mmol) of 2-(1-methylallyloxyaniline in 10 mL of pyridine. The crude product obtained is purified by vacuum flash chromatography (25% ethyl acetate/heptane) to give 5.31 g of a viscous liquid in 92.4% yield. The cis and trans isomers can be further separated by chromatography. The structures are confirmed by 1Hnmr analysis.
