Procedure
The title compound was prepared by a method analogous to that described for Example 3 using 2′-tert-butyl-4′,6′-dihydrospiro[piperidine-4,5′-pyrazolo[3,4-c]pyridin]-7′(2′H)-one hydrochloride salt (Intermediate 4) and 2-chloroquinoline-7-carboxylic acid (Intermediate 44). +ESI (M+H) 452.3; 1H NMR (400 MHz, CDCl3, δ): 8.12 (d, J=8.2 Hz, 1H), 7.98 (br. s., 1H), 7.88 (dd, J=8.4 Hz, 1H), 7.61 (dd, J=8.4, 1.6 Hz, 1H), 7.44 (d, J=8.6 Hz, 1H), 7.39 (s, 1H), 5.91 (br. s., 1H), 4.06-4.22 (m, 1H), 3.38-3.64 (m, 3H), 2.85 (br. s., 2H), 1.67-1.97 (m, 4H), 1.61 (s, 9H).
