Reaction Steps

A mixture of 4-amino-phenol (3 g, 0.027 mol) and 2-methylene-succinic acid dimethyl ester (4.35 g, 0.027 mol) was heated to 110° C. for 16 h. The dark brown glass was dissolved in EtOAc and purified by silica gel chromatography (20% EtOAc/hexane to EtOAC) to give the title compound as an orange oil. MS (ESI pos. ion) m/z: 236.2 (M+H). Calc'd Exact Mass for C12H13NO4: 235.24.
