Reaktionsschritte

The product from Example 8A (300 mg 1.8 mmol), methane sulfonic anhydride (313 mg, 1.8 mmol), and D1 EA (200 μL 5.4 mmol) were combined. After stirring, 1-(2-pyridinyl)piperazine (328 mg, 2.9 mmol) in 4 ml DCM was also combined and the mixture was processed as described in Example 8B to provide the title compound. 1H NMR (300 MHz, DMSO-d6) δ 2.57 (m, 4H) 3.50 (m, 4H) 3.84 (s, 2H) 6.63 (m, 2H) 6.81 (d, J=8.48 Hz, 1H) 7.32 (m, 2H) 7.52 (m, 2H) 7.77 (m, 1H) 7.90 (m, 1H).
