| titleOfInvention | PROCESS FOR THE PREPARATION OF 2-OXO-DIHYDROBENZO (D) (1,3) OXAZINES |
| abstract | The invention relates to a process for preparing 2-oxodihydrobenzo [d] [1,3] oxazines, of general formula I: (CF DRAWING IN BOPI) in which R ** 4, R ** 5, R ** 6, R ** 7 and R ** 8 may each represent a hydrogen atom, and their transformation into the corresponding o-amino-benzyl alcohols. Compounds I are prepared by dissolving or suspending an alcohol of general formula II: (CF DRAWING IN BOPI) in which R ** 4, R ** 5, R ** 6, R ** 7 and R * * 8 are as defined above, in an organic medium practically immiscible with water and the solution or suspension formed in the presence of a phase transfer catalyst is treated with an aqueous alkaline hypochlorite solution or hypobromite, the pH of which is at least 11 to obtain the desired compound. The products can be used as intermediates in the preparation of pharmaceuticals and dyes. |
