-

Yield:100-74-3 92%

Reaction Conditions:

with phenylboronic acid in 1,2-dichloro-ethane at 80; for 0.5 h;

Steps:

Deoxygenation of aliphatic and heteroaromatic amine N-oxides
General procedure: Phenylboronic acid (1.0 equiv. for aliphatic N-oxides and 1.5 equiv. for pyridine N-oxides) and tert-amine N-oxide (1 mmol) was stirred in dichloroethane (2 mL) at appropriate temperature (80 oC and 120 oC respectively) in a pressure tube. The progress of the reaction was monitoredby using TLC. After completion, the reaction mixture was diluted with ethyl acetate and washed with water and NaOH solution (1 normal, 3*5 mL). The organic layer was dried over anhydrous sodium sulfate, evaporated and subjected to the column chromatography to obtain pure products.
