Reaction Steps

To a vial containing 6-{[2-Chloro-3-(trifluoromethyl)phenyl]carbonyl}-3-(4-fluorophenyl)-2-methyl-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-c]pyridine (50 mg, 0.11 mmol) was added pyridinium chloride (270 mg, 2.30 mmol). The vial was flushed with N2 and heated to 170° C. for 30 min in a microwave reactor. To the reaction was added EtOAc and 1M NaOH. The layers were separated and the water layer was extracted with EtOAc three times. The combined organic layers were concentrated in vacuo and the residue was purified by HPLC (Gilson prep system, inertsil ODS-3, C18, 3 μm 30×100 mm column at 45° C., gradient of 5-70% MeCN/water with 0.05% TFA over 7 min, flow rate of 80 mL/min). The product was isolated as orange oil (9 mg, 19%) MS (ESI): mass calcd. for C20H14ClF4N3O, 423.8. m/z found, 424.2 [M+H]+. 1H NMR (500 MHz, CDCl3) δ 7.82-7.69 (m, 1H), 7.58-7.38 (m, 4H), 7.18-7.13 (m, 2H), 5.01 (m, 1H), 4.48-4.39 (m, 1H), 4.30-3.87 (m, 1H), 3.60-3.40 (m, 1H), 2.94 (t, J=5.8 Hz, 1H), 2.86-2.65 (m, 1H).
