Reaction Steps
3,2 ml of trichloromethylchloroformate (diphosgene) are added, with stirring, to a solution of 6,3 g of ethyl N′-methoxybenzoyl-N-phenyl-hydrazine-carboxylate in anhydrous tetrahydrofuran at ambient temperature. After one hour's stirring at ambient temperature the solvent is distilled off in vacuo and the residue remaining is recrystallised from ethanol. Yield: 6.5 g (96%), melting point: 112-115° C.
