実験手順

Step 5 A solution of (R)-benzyl 1-(1-cyano-7-(4-methylpiperazine-1-carbonyl)-9H-carbazol-4-yl)piperidin-3-ylcarbamate (108 mg, 0.196 mmol) in DMSO (2 mL) was treated with 22% aqueous potassium hydroxide (0.208 mL, 0.981 mmol), and then dropwise with a solution of 30% aqueous hydrogen peroxide (0.200 mL, 1.961 mmol). The mixture was stirred at rt for 2.5 h. Water was added, the resulting suspension was stirred at rt for 15 min, and the solid was collected by filtration, washed with water and dried to afford (R)-benzyl 1-(1-carbamoyl-7-(4-methylpiperazine-1-carbonyl)-9H-carbazol-4-yl)piperidin-3-ylcarbamate as an off-white solid (89 mg, 80%). 1H NMR (400 MHz, methanol-d4) δ 8.17 (d, J=8.13 Hz, 1H) 7.81 (d, J=8.35 Hz, 1H) 7.66 (s, 1H) 7.30 (d, J=7.91 Hz, 1H) 7.09-7.26 (m, 5 H) 6.82 (d, J=8.35 Hz, 1H) 4.90-5.03 (m, 2H) 3.87-3.99 (m, 1H) 3.57-3.68 (m, 1 H) 3.27-3.54 (m, 5H) 3.06-3.19 (m, 4H) 2.69-2.82 (m, 1H) 2.47-2.65 (m, 1H) 1.98-2.11 (m, 1H) 1.83-1.97 (m, 2H) 1.32-1.53 (m, 1H). Mass spectrum m/z 569.3 (M+H)+.
