Procedure

To a mixture of compound 10b (66 mg, 0.15 mmol) and pyridine (24 μL, 0.29 mmol) in DCM (5 mL) was added methanesulfonyl chloride (23 μL, 0.29 mmol). The resulting mixture was stirred at rt for 3 days. The mixture was then diluted with DCM (20 mL), and washed with 1 N HCl solution and brine. The organic layer was dried over MgSO4, filtered, and concentrated. The orange solid obtained was washed with methanol (2×5 mL), and dried in vacuo to give the title compound 47. 1H-NMR (400 MHz, DMSO-d6) δ (ppm): 10.09-10.17 (m, 1H), 8.64-8.83 (br.s., 1H), 8.25 (br.s, 1H), 8.06-8.22 (m, 3H), 7.83-8.06 (m, 3H), 7.63-7.80 (m, 3H), 7.36-7.48 (m, 2H), 6.46 (d, J=5.9 Hz, 1H), 4.04-4.18 (m, 4H), 3.79-3.97 (m, 4H), 3.14 (s, 3H). Mass Spectrum (LCMS, ESI pos.) Calcd. For C28H26N6O3S: 527.2 (M+H). Found 527.1.
