Reaction Steps

In accordance with the procedure of Example 1, 35.34g (0.15 moles) 5-(chloroformyloxypentyl)-1,3,4-dioxazol-2-one is reacted with 21.47g (0.165 moles) hydroxyethylmethacrylate in 75 ml 1,4-dioxane by adding 11.86g (0.15 moles) pyridine in 65 ml 1,4-dioxane over a 1 hour period at 19-21° C. After work-up, 47.30g of a slightly brown liquid is obtained which is analyzed by IR and NMR spectroscopy to be 5-[(methacryloyloxyethyl) formyloxypentyl]-1,3,4-dioxazol-2-one (yield 95.7%), having the following formula: ##STR16##
