Procedure

The above compound is obtained when (+)-7 -chloro-1,2,3,11a-tetrahydro-10-methyl-5 H-pyrrolo[2,1-c] [1,4] -benzodiazepin-5,11(10H)-dione (melting point 155°-157°C. is prepared from L-proline and 5-chloro-N-methylisatoic acid as described in Example 1) is treated with 1M borane in tetrahydrofuran as described in Example 1. The hydrochloride salt melts at 270°-272°C., [α]D 25 + 377° (1.03%) methanol).
