Versuchsvorschrift
To the solution of 5-chloro-2-cyclobutyl-1H-pyrrolo[2,3-c]pyridine (200 mg, 0.97 mmol) in EtOH (10 mL) and NH3.H2O (30 mL) was added CuSO4.5H2O (30 mg, 0.12 mmol). The reaction mixture was stirred under 3 MPa at 180° C. for 16 h. The mixture was extracted with ethyl acetate (3×30 mL). The extract was dried, concentrated in vacuo and purified by chromatography on silica gel (5-10% MeOH in ethyl acetate as eluant) to afford the pure 2-cyclobutyl-1H-pyrrolo[2,3-c]pyridin-5-amine (40 mg, 22% yield). 1H NMR (300 MHz, MeOH) δ: 8.02 (s, 1H), 6.72 (s, 1H), 6.11 (s 1H), 3.72-3.60 (m, 1H), 2.47-1.90 (m, 6H). MS (ESI): m/z [M+H+] 188.1.
