Procedure

Diethyl-1-methoxy-1-(3-acetoxyphenyl)methanephosphonate from Example 8 (10.29 g., 32.56 mmol) was dissolved in methanol (35 ml). Water (5 ml), and sodium bicarbonate (5 g, 60 mmol) were then added with stirring. After 48 hours at room temperature, the reaction mixture was concentrated in vacuo to remove methanol. The residue was treated with 150 ml dichloromethane and washed with water (2×50 ml). The organic layer was rotory evaporated and pumped at high vacuum to yield 8.21 g. (93%) of the product as a light yellow, viscous oil. Spectral data (Tables 5 and 9) are in accordance with the structure: ##STR35##
