実験手順
A mixture of 9.16 gm (0.05 mole) of phenyl 4-pyridyl ketone, 5.21 gm (0.05 mole) of ethylcarbazate and 75 ml of glacial acetic acid is heated at 100° C. for 8 hr. The acetic acid is removed in vacuo. The residue is slurried with ethyl ether and collected to yield 5.76 gm (39%) of the title compound having a melting point of 188.7° C.
