Versuchsvorschrift

To a solution of Intermediate 108e (0.20 mmol) in THF (2 mL) was added dimethylamine (2M in MeOH, 0.8 mL, 1.6 mmol) and stirring at RT was continued for 48 h. The crude reaction mixture was partitioned between EtOAc and water. The aqueous phase was extracted with EtOAc (×3) and the combined organic layers were washed with brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was purified by FCC on silica, using a gradient of 0-10% [2M NH3 in MeOH] in DCM followed by MDAP (Method 7) purification, to give the title compound (20 mg, 15%). LCMS (Method 5): Rt 3.34 min, m/z 666 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.24 (9H, s), 1.54-1.65 (2H, m), 1.67-1.77 (4H, m), 1.81-2.13 (4H, m), 2.16 (6H, s), 2.67 (2H, t, J=6.5 Hz), 3.13 (4H, t, J=5.3 Hz), 4.20 (2H, t, J=6.5 Hz), 4.79-4.87 (1H, m), 5.55 (1H, t, J=4.5 Hz), 6.26 (1H, s), 7.11-7.19 (2H, m), 7.26-7.41 (4H, m), 7.58-7.64 (3H, m), 7.99-8.05 (2H, m).
