反応手順
To a stirred solution of Example 233 (0.049 g, 0.15 mmol), 2-(1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (0.111 g, 0.29 mmol) and 1-methylpiperidine-4-carboxylic acid hydrochloride (0.034 g, 0.19 mmol) in DMF (0.5 mL) was added DIPEA (0.06 mL, 0.35 mmol). The reaction mixture was stirred at r.t. for 16 h. MeCN (1 mL) and water (1 mL) were added. The insoluble material was filtered, and the filtrate concentrated in vacuo. Purification by preparative HPLC (Method 6) gave the title compound (0.035 g, 51%) as a yellow solid. δH (CD3OD) 7.91 (1H, d, J 9.0 Hz), 7.37 (1H, d, J 2.3 Hz), 7.11 (1H, dd, J 8.9 and 2.3 Hz), 4.40-4.30 (2H, m), 4.20-4.09 (2H, m), 3.62 (2H, d, J 12.6 Hz), 3.17-3.02 (2H, m), 2.92 (3H, s), 2.89 (2H, s), 2.76-2.60 (1H, m), 2.34-1.91 (4H, m), 1.39 (6H, s). Exchangeable protons were not observed. LCMS (ES+) 456.21 (M+H)+, RT 1.80 minutes (Method 1).
