実験手順

To a solution of Intermediate 186c (293 mg, 0.44 mmol) and DIPEA (304 μL, 1.76 mmol) in DCM (10 mL) was added methanesulfonyl chloride (103 μL, 1.33 mmol). The reaction mixture was stirred at RT for 1 hour. The mixture was concentrated in vacuo. The residue was taken up in THF (2 mL) and dimethylamine solution in THF (2M, 3.3 mL) was added. The reaction mixture was heated at 60° C. in a sealed tube for 72 h. The reaction mixture was cooled to RT and concentrated in vacuo. The product was purified by HPLC using a gemini C18 column and using a gradient of 20-35%+0.1% Formic acid over 10 minutes. The combined fractions were evaporated under reduced pressure and crystallised by MeCN/Et2O to afford the title compound as a white solid (90 mg, 30%). LCMS (Method 3): Rt 3.01 min, m/z 706 [MH+]. 1H NMR (300 MHz, d6-DMSO): 0.91 (3H, d, J=6.7 Hz), 1.23 (9H, s), 1.46-1.54 (2H, m), 1.63-1.72 (2H, m), 1.75-1.76 (2H, m), 2.00-2.18 (2H, m), 2.43 (6H, s), 2.66 (2H, t, J=5.8 Hz), 2.85-2.95 (2H, m), 3.12-3.20 (4H, m), 4.10 (2H, t, J=5.4 Hz), 4.78-4.86 (1H, m), 5.52 (1H, t, J=4.0 Hz), 6.33 (1H, s), 6.95-6.99 (2H, m), 7.06-7.14 (2H, m), 7.19 (1H, dd, J=10.0 Hz), 7.25-7.32 (3H, m), 7.33-7.42 (2H, m), 7.58 (1H, d, J=10.6 Hz), 7.63 (1H, d, J=1.8 Hz), 8.17 (1H, s).
