Reaction Steps

To a solution of 3-methoxy-4-nitrobenzoic acid (1 equiv) in toluene (0.21 M) was added triphenyl phosphine (1.5 equiv), carbon tetrabromide (1.6 equiv), TEA (2 equiv) and 2-aminoethanol (0.7 equiv). Then the resulting mixture was stirred at 80° C. for 1 h. The reaction mixture was filtered, the filtrate was concentrated and the crude was purified by reverse phase HPLC (10%-95% acetonitrile in water) to give the title compound (34% yield) as a yellow solid. MS (ESI) m/z 223.1 [M+1]+.
