4-Chloro-2,3-dimethylpyridine 1-oxide Chemical Properties,Uses,Production
Chemical Properties
Pale Yellow Solid
Uses
An intermediate in the synthesis of rabeprazole (R070500).
Synthesis
83.0 g (0.49 mol) of 4-nitro-2,3-dimethylpyridine N-oxide and 90 g (1.54 mol) of NaCl were admixed with 1350 ml of CH3CN, 180 ml of aq. HCl (36%) and 16.6 g of benzyltributylammonium chloride, and the resulting suspension was boiled under reflux with stirring for 12 h. The resulting reaction mixture was adjusted to PH=9 using 350 ml of 20% NaOH, wherefor the existing precipitate largely dissolved. The organic phase was separated off, water was added to the aqueous phase until the precipitate had completely dissolved, and it was subsequently extracted using dichloromethane. The organic phases were combined and the solvent was removed under reduced pressure. 76.6 g (98.5%) of 4-Chloro-2,3-dimethylpyridine 1-oxide were obtained.
