Glutaric anhydride → HCID 23367636, compound

Participants

Reaction Steps

These materials were prepared using the procedures outlined in Steps 2 and 3 of Preparatory Example 2, except starting with 5-[4-(benzyloxycarbonyl)piperazinocarbonyl]-5H-dibenzo[b,f]azepine in place of the N-[3-(benzyloxycarbonylamino)propyl]carbamazepine in step 2, and thus the product 5-(Piperazinocarbonyl)-5H-dibenzo-[b,f]azepine Hydrobromide in place of the product of step 2, and glutaric anhydride in place of succinic anhydride in the procedures of step 3. The residue (2B) was crystallized from ethyl acetate (10 mL) and petroleum ether (2 mL), placed in a freezer, and filtered to give the acid.
