実験手順

A solution of tert-butyl 1-((5R)-7-acetoxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)-5-chlorospiro[indoline-3,4′-piperidine]-1′-carboxylate (0.170 g, 0.331 mmol) in 2:1 THF:H2O (1.8 mL) was cooled to about 0° C. LiOH—H2O (0.034 g, 0.83 mmol) was added and the reaction was stirred at about room temperature for 4 hours. The reaction was quenched by the addition of 1N HCl to pH 6. The aqueous phase was extracted with EtOAc. The combined organics were washed with brine, dried over MgSO4, filtered and concentrated. The crude residue was purified by column chromatography (30-70% EtOAc/Hexane) to yield tert-butyl 5-chloro-1-((5R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-carboxylate (0.065 g, 42%). LCMS (APCI+) m/z 471, 473 [M+H]+; Rt=3.82 min.
