実験手順

A solution of tert-butyl 5-chloro-1-((5R,7R)-5-methyl-7-(4-nitrobenzoyloxy)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-carboxylate (0.020 g, 0.032 mmol) in THF:H2O (2:1, 0.3 mL) was cooled to about 0° C. and treated with LiOH—H2O (0.0027 g, 0.065 mmol). The reaction was stirred at about 0° C. for about 5 minutes, followed by about room temperature for 1.5 hours. The reaction was concentrated and diluted with saturated NaHCO3 and extracted with EtOAc. The combined extracts were washed with brine, dried over MgSO4, filtered and concentrated. Crude residue was purified by preparative HPLC to yield tert-butyl 5-chloro-1-((5R,7R)-7-hydroxy-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-carboxylate (0.005 g, 36%). LCMS (APCI+) m/z 471, 473 [M+H]+; Rt=4.11 min.
