Reaction Steps

2-Allylphenol (4.70g = 0.035 moles) and 2.76g (0.035 moles) pyridine dissolved in 11 ml 1,4-dioxane are added over a 1 hour period to a well stirred solution of 8.25g (0.035 moles) 5-(chloroformyloxypentyl)-1,3,4-dioxazol-2-one in 25 ml 1,4-dioxane at 40° C. Stirring is continued at 53° C for 11/2 hours. The product is then dissolved in 150 ml chloroform, washed 3 times with ice water, dried over Drierite and evaporated under vacuum. The residue, 11.67g of yellow liquid is analyzed by IR and NMR spectroscopy and found to contain 69.4 wt. % of 5-[(o-allylphenyl)-formyloxypentyl]-1,3,4-dioxazol-2-one (yield = 69.4%), having the following structural formula: ##STR15##
