35 g (0.2 mol) of 4-chlorobenzoyl chloride were warmed to 90° to 100° C. under a nitrogen atmosphere. 46 g of 6-methoxy-(6H)-dibenz[c,e][1,2]oxaphosphorin were added dropwise while stirring. The internal temperature was then increased gradually to 130° C. When the reaction was complete, the mixture was digested with 50 ml of toluene. 60 g (85% of theory) of the abovementioned substance of melting point 125° to 131° C. were obtained.
