実験手順

To a solution of compound 145-H (0.46 g, 1.52 mmol) in pyridine (4.6 mL), cooled to 0° C., was added benzenesulfonyl chloride (0.206 mL, 1.60 mmol), and the reaction was heated to 50° C. for 72 h. Additional benzenesulfonyl chloride (0.412 mL, 3.20 mmol) was added and the reaction mixture was heated at 50° C. for an additional 16 h. The solvent was evaporated in vacuo, the residue dissolved in dichloromethane and washed with aqueous sodium bicarbonate. The aqueous layer was acidified with 1N HCl, extracted with dichloromethane, and the organic layer was evaporated in vacuo to afford a yellow solid (0.22 g, 36%) as a 1/3.5 mixture of the 3-bromo- and 3-chloro-substituted compounds, 145-Ia and 145-Ib, respectively. 1H-NMR (DMSO-d6): δ 7.1-7.2 (m, 1H), 7.4-7.6 (m, 3H), 7.8 (m, 2H), 8.1-8.2 (m, 1H), 8.25-8.35 (m, 1H); MS: m/z 465 and 509 (MH+).
