Participants

Reaction Steps

To a solution of 85 mg (0.315 mmole) of 1,3-dihydro-3(RS)-amino-5-(2-fluorophenyl)-2H-1,4-benzodiazepin-2-one in 8 ml of dry tetrahydrofuran was added 4-chlorophenylisocyanate (40 μl, 0.315 mmole) at room temperature. Within 15 minutes a flocculant, white precipitate formed. Stirring was continued for 8 hours more and the reaction mixture was filtered. The collected solids were washed with hot methanol and dried in vacuo to give the analytical product: m.p. 278° C.
