実験手順
A mixture of 14.0 g (79 mmol) of 6-methylisatoic acid anhydride, 7.04 g (79 mmol) of sarcosine and 80 ml of dimethyl sulphoxide is stirred at 110° C. for 3 hours. The red coloured solution is evaporated in a high vacuum. The residue is treated with 80 ml of ethanol, the product crystallising out. There is obtained 3,4-dihydro-4,6-dimethyl-2H-1,4-benzodiazepine-2,5(1H)-dione of melting point 200°-202° C.
