実験手順

To a solution of 4-cyclohexylcyclohexanone (27.04 g) and acetic acid (3 ml) in CH2Cl2 (400 ml) was added a solution of diethyl phosphorohydrazidate (28.91 g) in CH2Cl2 (100 ml). The reaction was stirred at room temperature for 27 hours and then was concentrated under reduced pressure. Toluene was added (2×) and removed under reduced pressure in order to aid in the removal of acetic acid by codistillation. The residual yellow liquid was the product and was used without further purification. TLC Rf=0.52 (20% acetone in CH2Cl2, silica gel).
