Procedure

A mixture of 8.7 g (0.03 mol) of 6-iodoisatoic acid anhydride, 3.2 g (0.036 mol) of sarcosine and 25 ml of dimethylacetamide is heated to boiling under reflux for 1 hour. After cooling and dilution with water, the mixture is extracted with chloroform. The chloroform extracts are dried and evaporated. After recrystallization of the crude product from methylene chloride/ether, there is obtained 3,4-dihydro-6-iodo-4-methyl-2H-1,4-benzodiazepine-2,5(1H)-dione of melting point 214°-217°.
