(0.2 moles) of methyl carbazate and 100 ml. of acetonitrile 33.7 g (0.2 moles) of β-phenylpropionyl chloride are added dropwise. The reaction mixture is heated to boiling for 15 hours, clarified and cooled. The crystals are filtered off. Thus 36.85 g of the desired compound are obtained, yield 80.7% m.p.: 118° C.
