Conditions

Temperature
110 °C

Procedure

Ethyl 2-(4-vinylbenzyl)-3,3-(ethylenedioxy)butanoate polymer (formed in Example 3) (1.9 g, 7.7 mmol) was dissolved in g-butyrolactone (30 ml). A solution of NH4OH (30% in water) was added and the solution warmed to 110 ° C. for 5 hours. The resultant solution was made slightly acidic with the addition of HCl and the ethyl 2-(4-vinylbenzyl)-3,3-(ethylenedioxy)butanoic acid polymer precipitated into toluene and dried as a white powder (0.6g).

Workup
