Reaction Steps

A solution of dimethylamine in tetrahydrofuran (2.2 mL, 4.4 mmmol, 2.0 M) was added to 2′-tert-butyl-1-(2-chloroquinoline-7-carbonyl)-4′,6′-dihydrospiro[piperidine-4,5′-pyrazolo[3,4-c]pyridin]-7′(2′H)-one (100 mg, 0.2 mmol). The reaction vessel was sealed and the mixture was heated to 70° C. for 15 hours. The reaction was cooled to room temperature and concentrated. Purification by reversed-phase HPLC gave the title compound (25 mg, 25%). +ESI (M+H) 461.2; HPLC retention time 1.96 minutes (Method A).
