PROCESS FOR TRANSFORMING 10,11-EPOXY-10,11-DIHYDRO-5H-DIBENZO-SQUARE BRACKET-B,F-SQUARE BRACKET CLOSED-AZEPINE -5-CARBOXAMIDE FOR PRODUCING 10-OXO-10,11-DIHYDRO-5H-DIBENZ-SQUARE BRACKET-B,F-SQUARE BRACKET CLOSED-AZEPINE-5-CARBOXAMIDE

摘要

Process for the rearrangement of 10,11-epoxy-10,11-dihydro- 5H-dibenz¢b,f!azepine-5-carboxamide to 10-oxo-10,11- dihydro-5H-dibenz¢b,f!azepine-5-carboxamide The invention relates to a process for the rearrangement of 10,11-epoxy-10,11-dihydro-5H-dibenz¢b,f!azepine 5-carboxamide of the formula to 10-oxo-10,11-dihydro-5H-dibenz¢b,f!azepine-5-carboxamide of the formula which process comprises performing the rearrangement by means of a bromide or iodide of lithium, magnesium or calcium in the dry form, or in the form of their known compounds with water (hydrates) or with organic substances, in a suitable solvent within a temperature range of 20 - 120.degree.C, preferably of 40 - 80.degree.C.
