Procedure

Prepared according to Procedure B with 1m (500 mg, 1.59 mmol) and chloroacetyl chloride (0.38 mL, 4.77 mmol) in acetic acid (10 mL). Purified by recrystallization from isopropanol to afford 359 mg of a white crystalline solid (61%). 1H NMR (CDCl3) δ: 8.51 (dd, J=1.0, 8.0 Hz, 1H); 8.14 (d, J=7.3 Hz, 1H); 7.65 (dd, J=2.5, 5.6 Hz, 1H); 7.62 (d, J=3.9 Hz, 1H); 7.48-7.60 (m, 3H); 4.44 (d, J=12 Hz, 1H), 4.12 (d, J=12 Hz, 1H). MS (ES): m/z 373.0 (M+).
