10-methyl-2,3-dihydro-1H-pyrrolo[2,1-c][1,4]benzodiazepine-5,11(10H,11aH)-dione → 8-Chloro-1,2,3,5,10,11a-hexahydro-10-methyl-11 H-pyrrolo[2,1-c] [1,4] benzodiazepin-11-one

Participants

Reaction Steps

This compound is obtained when (+)-8-chloro-1,2,3,11 a-tetrahydro-10-methyl-5 H-pyrrolo[2,1-c] [1,4] benzodiazepin-5,11(10H)-dione (melting point 191° -194°C. prepared from L-proline and 4-chloro-N-methylisatoic anhydride is described in Example 1) is substituted for (+) 1,2,3,11a-tetrahydro-10 -methyl-5 H-pyrrolo[2,1-c] [1,4] benzodiazepin-5,11(10H)-dione in the process of Example 1.
