실험 절차

A solution of 1-(1H-indol-2-yl)-3-piperidin-4-ylimidazo[1,5-a]pyrazin-8-amine hydrochloride (30 mg, 0.09 mmol), 2-formylquinoline (17 mg, 0.11 mmol) and triethylamine (0.019 mL, 0.14 mmol) in 1,4-dioxane (1 mL) was treated with sodium cyanoborohydride (5.7 mg, 0.090 mmol) and microwaved at 300 watts, 120° C. for 20 min. The mixture was concentrated in vacuo, the residue was dissolved in methanol loaded onto an SCX ion exchange cartridge, and then eluted with 1M NH4OH in methanol. The semi-pure material thus obtained was then subjected to semi-preparative HPLC to afford desired product. 1H NMR (400 MHz, MeOD) δ ppm 2.13-2.33 (m, 4H), 2.90 (t, J=10.86, 9.60 Hz, 2 H), 3.47 (d, J=10.11 Hz, 2 H), 4.29 (s, 2 H), 6.74 (s, 1 H), 7.02-7.11 (m, 2 H), 7.19 (t,J=8.08, 7.07 Hz, 1 H), 7.47 (d, J=9.09 Hz, 1 H), 7.58-7.65 (m, 3 H), 7.69 (d, J=8.59 Hz, 1 H), 7.80 (t, J=8.34, 6.82 Hz, 1 H), 7.96 (d, J=7.33 Hz, 1 H), 8.08 (d, J=834 Hz, 1 H) and 8.39 (d, J=8.59 Hz, 1 H). MS (ES+): m/z 474.23 [MH+].
