実験手順
A mixture of 24.8 g. of (-)-1-(N-methylanthraniloyl)-proline and 300 ml. of benzene is stirred and 12.0 g. of thionyl chloride is added dropwise. The mixture is heated at reflux temperature for 2 hours, cooled, washed twice with water and concentrated to recover the (+)-1,2,3,11a-tetrahydro-10-methyl-5H-pyrrolo[2,1-c][1,4]benzodiazepin-5,11(10H)-dione.
