Procedure: To a stirred solution of 1.0 g of 1-oxyl-4-amino-2,2,6,6-tetramethylpiperidine in 75 mL of dry toluene is added dropwise 0.65 mL of butyl isocyanate. The reaction mixture is stirred for 16 hours. The solution is then concentrated to yield the title compound as a red oil. The solution is then concentrated

Procedure: To a stirred 0° C. solution of 1.0 g of 1-oxyl-4-amino-2,2,6,6-tetramethylpiperidine and 0.65 g of triethylamine in 10 mL of methylene chloride is added dropwise a solution of 0.95 g of octanoyl chloride in 5 mL of methylene chloride. After the addition is complete, the reaction mixture is allowed to warm to ambient temperature. After two more hours, the reaction mixture is washed with 1% aqueous sodium hydroxide and finally water. The organic phase is dried over anhydrous magnesium sulfate, filtered and concentrated. The title compound is isolated as a red oil after column chromatography. After the addition After two more hours, the reaction mixture is washed with 1% aqueous sodium hydroxide and finally water The organic phase is dried over anhydrous magnesium sulfate filtered concentrated
