Reaction Conditions

Reaction Steps

2.15 ml Benzoylchloride are dropwise added to a solution of 4.42 g 2,2,6,6-tetramethyl-1-phenyldiazenyl-piperidin-4-ol (see example 1) and 0.1 g 4-dimethylaminopyridine in 35 ml pyridine. The resulting mixture is stirred 4 hours at 23° C., then diluted with 300 ml ice-water. The precipitate is filtered off and recrystallized twice from methanol to afford 4.43 g of benzoic acid 2,2,6,6-tetramethyl-1-phenyldiazenyl-piperidin-4-yl ester as an off-white solid, m.p. 89-91° C.
