実験手順

Methyl 3-formyl-1H-pyrrolo[2,3-b]pyridine-4-carboxylate (160 mg, 0.784 mmol) and tert-butyl 4-aminopiperidine-1-carboxylate (188 mg, 0.940 mmol) were combined in MeOH (3 mL) and THF (3 mL) at 50° C. for 3 H. Then sodium borohydride (59 mg, 1.567 mmol) was added at room temperature and allowed to stir for 10 min. The mixture was quenched with water and extracted with ethyl acetate. The organics were dried over MgSO4 and concentrated in vacuo to give methyl 3-((1-(tert-butoxycarbonyl)piperidin-4-ylamino)methyl)-1H-pyrrolo[2,3-b]pyridine-4-carboxylate (60 mg) which was carried on to the next step. 1H NMR (400 MHz, CD3OD) δ 8.32 (d, 1H, J=5.1 Hz), 7.61-7.62 (m, 2H), 4.07-4.13 (m, 4H), 4.01 (s, 3H), 2.81-2.84 (m, 3H), 1.96-1.98 (m, 2H), 1.45-1.47 (m, 2H), 1.45 (s, 9H). [M+H] found 389.
