Versuchsvorschrift
3.16 g of 2-(methylthio)-7-chloro-5-phenyl-3H-1,5-benzodiazepin-4-one and 1.41 g of t-butylcarbazate in 60 ml of dimethyl formamide are refluxed for 20 hours while a slow stream of nitrogen is bubbled through the reaction. The reaction is worked up as described in Example 29, Method A, to give the title compound.
