참여 물질

반응 단계

100 g of 10-methoxycarbamazepine in 1000 ml water and 69.24 g of oxalic acid solution were heated to 90° C. and maintained for about 17 hrs. After completion of the reaction the reaction mixture was cooled to room temperature (RT). The resulting reaction mass was filtered and washed with 1000 ml of DM water. The wet material obtained was charged with isopropyl alcohol and DM water. The obtained reaction mixture was heated to reflux for about 2 h. The reaction mixture was cooled to 15-25° C., filtered and washed with 100 ml of IPA-water mixture. The resulting compound is dried at 60° C. for 6 h to produce 90 g of Oxcarbazepine.
