Versuchsvorschrift

A flask was charged with Pd2 dba3 (0.233 g, 0.254 mmol) and Xantphos (0.221 g, 0.381 mmol) and purged with nitrogen. The flask was then charged with tert-butyl (1′-benzylspiro[indoline-3,4′-piperidine]-4-yl)methylcarbamate (1.04 g, 2.54 mmol), 4-chloro-5-isopropyl-6,7-dihydro-5H-cyclopenta[d]pyrimidine (0.500 g, 2.54 mmol), Cs2CO3 (1.24 g, 3.81 mmol) and toluene (12.7 mL) The reaction was purged with nitrogen and heated to 100° C. overnight. The reaction was cooled to room temperature and filtered through celite, then GFF, and concentrated under reduced pressure. The crude residue was purified by column chromatography (1-5% MeOH/DCM) to yield tert-butyl (1′-benzyl-1-(5-isopropyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-4-yl)methylcarbamate (1.0 g, 69%). LCMS (APCI+) m/z 568.3 [M+H]+; Rt=4.30 min.
