Procedure

4N HCl in dioxane (0.1 mL) was added to a solution of tert-butyl 4-((tert-butoxycarbonyl(isopropyl)amino)methyl)-1-((5R,7 S)-7-fluoro-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-carboxylate (12 mg, 0.020 mmol) in DCM (0.3 mL). The reaction mixture was stirred at room temperature overnight. The solvents were evaporated. The crude residue was taken up in MeOH and basified with 7N ammonia in MeOH. After evaporation of the solvent, the residue was purified by column chromatography (4% 7 N ammonia in MeOH/DCM) to yield the free base, which was taken up in DCM and acidified with 2N HCl in Et2O. Removal of the solvents afforded N-((1-((5R,75)-7-fluoro-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-4-yl)methyl)propan-2-amine trihydrochloride (9 mg, 88%) as a solid. LCMS (APCI+) m/z 410 [M+H]+; Rt=1.55 min.
