実験手順

To a solution of 4-benzyloxy-1-(5-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-7-yl)pyridin-2(1H)-one (100 mg, 0.26 mmol) in DMF (3 mL) was added O-(7-azabenzotriazol-1-yl)-N,N,N′N′-tetramethyluronium hexafluorophosphate (HATU) (148 mg, 0.389 mmol), 3-(pyrrolidin-1-yl)propanoic acid hydrochloride (56 mg, 0.31 mmol), and Et3N (73 μL, 0.52 mmol). The reaction mixture was stirred at room temperature under Ar until the reaction was complete. The reaction was quenched with water and extracted with CH2Cl2. The organic layer was washed with H2O and 5% LiCl, dried with Na2SO4, filtered and concentrated. Purification by flash column chromatography (silica gel, 5% CH3OH in CH2Cl2) gave 4-(benzyloxy)-1-(5-methyl-2-(3-(pyrrolidin-1-yl)propanoyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-7-yl)pyridine-2(1H)-one as a yellow foam. The free base was converted to the HCl salt to give the title compound (75 mg, 86%) as a yellow solid: mp 110-115° C.; 1H NMR (500 MHz, CD3OD) δ 7.79-7.76 (m, 1H), 7.61-7.55 (m, 1H), 7.49-7.36 (m, 6H), 7.05-7.02 (m, 1H), 6.55-6.52 (m, 1H), 6.33-6.32 (m, 1H), 5.26 (s, 2H), 4.06 (t, J=5.5 Hz, 1H), 3.94 (t, J=5.5 Hz, 1H), 3.70-3.69 (m, 5H), 3.54-3.50 (m, 2H), 3.18-2.89 (m, 8H), 2.18-2.04 (m, 4H); ESI MS m/z 511 [M+H]+; HPLC (Method B) 97.7% (AUC), tR=13.6 min.
