Procedure

The procedure of Example 1 is repeated using 1.95 g (12.5 mmol) of 1-oxyl-2,2,6,6-tetramethyl-4-hydroxypiperidine, 3.10 g (30 mmol) of tert-butyl nitrite, 7.5 mg (0.012 mmol) of (S,S)-(+)-N,N-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminocobalt(II) mmol) in 100 mL of chlorobenzene and 5.60 g (25 mmol) of 2-allyloxyaniline in 20 mL of chlorobenzene. The crude product obtained is purified by vacuum flash chromatography (25% ethyl acetate/heptane) to give 2.22 g of a viscous liquid in 61.5% yield.
