61.8 g (0.4 mol) of 2-methylbenzoyl chloride were warmed to 80° C. under a nitrogen atmosphere. 92 g (0.4 mol) of 6-methoxy-(6H)-dibenz[c,e][1,2]-oxaphosphorin were added dropwise over the course of two to three hours while stirring. The temperature was then increased in steps to 115° C. When the reaction was complete, 50 ml of acetone were added at room temperature. After crystallization, 103 g (77% of theory) of the above-mentioned compound of melting point 102° to 104° C. were obtained.
