The product mixture was diluted with water (5 mL), extracted twice with EtOAc (5 mL), the combined organic phases were washed with brine (5 mL), dried with Na2SO4 and concentrated to give 13 mg of a white solid. 1H NMR (400 MHz, CD3OD) d 7.46 (s, 1 H), 6.64 (s, 1 H), 3.16 (m, 3 H), 2.94 (m, 3 H), 2.81 (m, 1 H), 1.35 (d, J=7 Hz, 3 H). MS calculated for C11H14INO+H: 304, observed: 304.
