Prepared according to Procedure B with 1n (500 mg, 1.68 mmol) and chloroacetyl chloride (0.40 mL, 5.05 mmol) in acetic acid (10 mL). Purified by chromatography in CH2Cl2 followed by recrystallization from isopropanol to afford 232 mg of a light-brown solid (39%). 1H NMR (CDCl3) δ: 8.92 (s, 1H); 8.29 (s, 1H); 8.81 (d, J=8.3, 1H); 8.32 (d, J=8.3 Hz, 1H); 7.51-7.69 (m, 4H); 7.55 (d, J=5.2 Hz, 1H); 7.53 (d, J=3.8 Hz, 1H); 4.43 (d, J=12 Hz, 1H), 4.12 (d, J=12 Hz, 1H). MS (ES): m/z 355.0 (M+).
