Participants

Reaction Steps

The procedure of Example 1 is repeated using 23.32 g (240 mmol) of bis(1-oxyl-2,2,6,6-tetramethylpiperidin-4-yl) sebacate, 30.9 g (300 mmol) of tert-butyl nitrite, 35.5 mg (0.059 mmol) of (S,S)-(+)-N,N-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminocobalt(II), 120 mL of pyridine and 22.32 g (240 mmol) of aniline at 70° C. A total of 10 g of the 47 g of crude product is purified by vacuum flash chromatography (1% ethyl acetate in heptane) to give 4.0 g of the title compound as a yellowish solid in 47.9% yield. The structure is confirmed by 1Hnmr, elemental and mass spectrographic analyses.
