実験手順

To a stirred solution of 3-aminoisoquinoline (75 mg, 0.52 mmol) and 2-({2-[(morpholine-4-carbonyl)-amino]-pyridin-4-ylmethyl}-amino)-benzoic acid methyl ester (149 mg, 0.40 mmol) in DCE (6 mL) at 0° C., under argon, was added trimethylaluminium (2M in toluene, 0.4 mL, 0.8 mmol). The reaction was heated at 120° C. (bath temperature) for 3 hours. On cooling the reaction was diluted with aqueous sodium hydrogencarbonate solution and extracted with dichloromethane. The organic phase was washed with water, dried and concentrated in vacuo. The residue was purified by chromatography on Isolute® flash NH2 (Separtis) (Eluant: EtOAc) to give morpholine-4-carboxylic acid (4-{[2-(isoquinolin-3-ylcarbamoyl)-phenylamino]-methyl}-pyridin-2-yl)-amide (60 mg, 32%) as a resin; 1H-NMR (300 MHz, d6-DMSO) 10.69 (1H, s), 9.21 (1H, s), 9.18 (1H, s), 8.60 (1H, s), 8.16-8.20 (2H, m), 8.10 (1H, d), 7.96 (1H, d), 7.90 (1H, d), 7.82 (1H, d), 7.75 (1H, t), 7.57 (1H, t), 7.28 (1H, t), 6.98 (1H, d), 6.63 (1H, t), 6.58 (1H, d), 4.48 (2H, d), 3.55-3.59 (4H, m), 3.41-3.45 (4H, m); m/z (ES+) 483 [M+H]+, 242.
