실험 절차

A mixture of 56.3 mg (0.150 mmol) of 3-(6-fluoropyridin-2-yl)-5-(pyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-c]pyridine and 211 mg, 0.90 mmol) of benzyl piperidin-4-ylcarbamate in 1.0 ml of dimethyl sulfoxide was heated at 100° C. for 24 hours. The mixture was mixed with water and extracted with ethyl acetate. The organic extracts were washed with water, 1% aqueous citric acid, water, brine, dried over MgSO4 and concentrated. The residue was heated in a mixture of 4 M of hydrogen chloride in 6 ml of dioxane and 2 ml of conc. hydrochloric acid at 60° C. for 18 hours. The mixture was concentrated in high vacuum and triturated with ethyl ether. The solid material was filtered out and washed with ethyl ether to give 144. Yield 13.7 mg (19%) over two steps. ESI MS m/z 372.1 (M+1). 1H NMR (400 MHz, DMSO): 14.17 (s, 1H), 9.41 (s, 1H), 9.29 (s, 1H), 8.99 (s, 1H), 8.93 (d, J=7.9 Hz, 1H), 8.87 (d, J=5.0 Hz, 1H), 8.14 (s, 3H), 8.07-7.99 (m, 1H), 7.76-7.69 (m, 1H), 7.51 (d, J=7.4 Hz, 1H), 6.99 (d, J=8.5 Hz, 1H), 4.52 (d, J=13.3 Hz, 3H), 3.40 (s, 2H), 3.12 (t, J=11.9 Hz, 2H), 2.08 (d, J=10.1 Hz, 2H), 1.66 (dt, J=12.0, 8.5 Hz, 2H)
