반응 단계
Prepared according to Procedure B with 1j (750 mg, 2.88 mmol) and chloroacetyl chloride (0.69 mL, 8.63 mmol) in acetic acid (15 mL). Purified by chromatography in CH2Cl2, followed by recrystallization from isopropanol to afford 340 mg of a white solid (37%). 1H NMR (CDCl3) δ: 7.69 (d, J=2.1 Hz, 1H); 7.68 (q, J=7.4 Hz, 1H); 7.54 (dd, J=2.2, 7.0 Hz, 1H); 7.35-7.47 (m, 3H); 7.21-7.25 (m, 1H); 4.27 (d, J=12 Hz, 1H); 4.11 (d, J=12 Hz, 1H); 2.18 (s, 3H). MS (ES): m/z 319.0 (M+).
