Procedure

Prepared according to Procedure B with 1c (500 mg, 1.89 mmol) and chloroacetyl chloride (0.45 mL, 5.67 mmol) in acetic acid (10 mL). Purified by extraction from aqueous K2CO3, followed by recrystallization from isopropanol to afford 501 mg of a yellow crystalline solid (82%). 1H NMR (CDCl3) δ: 8.32 (dd, J=6.0, 8.9 Hz, 1H); 7.59-7.66 (m, 1H); 7.50-7.55 (m, 3H); 7.44 (dd, J=2.4, 9.4 Hz, 1H); 7.27 (dt, J=2.5, 8.5 Hz, 1H); 4.37 (d, J=12 Hz, 1H), 4.07 (d, J=12 Hz, 1H). MS (ES): m/z 323.0 (M+).
