After a mixture of 28.5g of 9-chloromethylanthracene and 62.3g of triethyl phosphite was heated at a temperature of 140° C for 2 hours with stirring, the mixture was cooled to a room temperature to obtain light yellowish needle-like crystalline product. The crystalline product was filtered off and washed with petroleum ether, and then dried. A crude product was obtained in a yield of 34.4g (83.8%). A pure crystalline product of diethyl 9-anthrylmethylphosphonate (m.p. 103.5° C - 104° C) was obtained by the recrystallization of the crude product from n-hexane in a yield of 31.2g.
