실험 절차

A solution of 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, 0.14 mmol) and TEA (0.038 ml, 0.28 mmol) in DCM was cooled to about 0° C. To the mixture was added 4-nitrobenzoyl chloride (0.031 g, 0.17 mmol). The reaction was stirred at about 0° C. for about 5 minutes, then warmed to about room temperature and stirred for 1.5 hours. The reaction was diluted with DCM and saturated NaHCO3. The combined extracts were washed with brine, dried over MgSO4, filtered and concentrated. The crude residue was purified by column chromatography (30-50% EtOAc/Hexane) to yield 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, 23%). LCMS (APCI+) m/z 620, 622 [M+H]+; Rt=4.65 min, and to yield tert-butyl 5-chloro-1-((5R,7S)-5-methyl-7-(4-nitrobenzoyloxy)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-carboxylate (0.029 g, 29%). LCMS (APCI+) m/z 620, 622 [M+H]+; Rt=4.66 min.
