반응 단계
A solution of 13.6 g (0.0768 mol) of 6-methylisatoic acid anhydride and 8.8 g (0.0768 mol) of L-proline is heated at 110° C. for 1 hour in 75 ml of dimethyl sulphoxide. Subsequently, the mixture is evaporated to dryness in a high vacuum and the residue is recrystallised from ethyl acetate with the addition of active carbon. There is obtained (S)-1,2,3,11a-tetrahydro-6-methyl-5H-pyrrolo[2,1-c][1,4]benzodiazepine-5,11(10H)-dione of melting point 212°-214° C.
