실험 절차

A mixture of (R)-2-(3-(5-chloro-1-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-yl)propyl)isoindoline-1,3-dione (9 mg, 0.02 mmol) and 2M MeNH2 in MeOH (0.5 mL) was stirred at about room temperature overnight. The solvent was evaporated. The residue was purified by column chromatography (DCM:7N ammonia in MeOH, 8:1) to give (R)-3-(5-chloro-1-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-yl)propan-1-amine as a free base, which was taken up in DCM and acidified with 2N HCl in ether. Removal of the solvents under reduced pressure afforded (R)-3-(5-chloro-1-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-yl)propan-1-amine trihydrochloride (5 mg, 74%) as a solid. LCMS (APCI+) m/z 412, 414 [M+H]+; Rt=2.47 min.
