Versuchsvorschrift

The preparation of benoxacor, a safener in the use of herbicides, is a three-stage process: in the first stage, o-nitrophenol is reacted with chloroacetone to give o-nitrophenoxyacetone; in the second stage, the compound is hydrogenated so as to obtain a benzoxazine, which is then acylated. This process is described in EP1283829.
