Procedure
Prepared according to the general procedure described in Example 92, by reacting 4-methoxy-3-(1H-pyrazol-4-yl)-1-trityl-1H-pyrazolo[4,3-c]pyridine with tetrahydrofuran-3-yl methanesulfonate to give the title compound as a mixture of enantiomers. The enantiomers were separated via supercritical fluid chromatography to give the separated enantiomers. (7.9 mg, 7.7 mg, total yield 24% over two steps). LC-MS (Method G): m/z=286.1 [M+H]+; 2.97 min. 1H-NMR (400 MHz, DMSO): δ 13.27 (s, 1H), 8.32 (s, 1H), 8.04 (s, 1H), 7.85 (d, J=6.0, 1H), 7.09 (d, J=6.0 1H), 5.17-5.09 (m, 1H), 4.06 (s, 3H), 4.05-3.98 (m, 2H), 3.95 (dd, J=9.4, J=3.7, 1H), 3.91-3.83 (m, 1H), 2.47-2.36 (m, 1H), 2.36-2.25 (m, 1H).
