Using the method described in Example I, 6 g (0.02 mole) of diethyl (3-ethyl-isoxazol-5-yl)-methanephosphonate and 4.4 g (0.02 mole) of o-(1-methoxyethoxy)-benzaldehyde are reacted and the product is recrystallized from isopropanol. 1.7 g (32% of theory) of colorless crystals, of melting point 175°-176° C., are obtained.
