Procedure
Prepared according to Procedure B with 1l (2.6 g, 9.41 mmol) and chloroacetyl chloride (2.2 mL, 28.2 mmol) in acetic acid (40 mL). Purified by chromatography in CH2Cl2, followed by recrystallization from isopropanol to afford 874 mg of a pale yellow solid (28%). 1H NMR (CDCl3) δ: 7.55-7.74 (m, 2H); 7.47-7.54 (m, 2H); 7.34 (dd, J=1.7, 7.8 Hz, 1H); 7.13 (dt, J=1.2, 7.7 Hz, 1H); 7.08 (dd, J=1.0, 8.4 Hz, 1H); 4.29 (d, J=12 Hz, 1H); 4.11 (d, J=12 Hz, 1H); 3.80 (s, 3H). MS (ES): m/z 335.0 (M+).
