Reaction Steps

A pear-shaped flask was charged with Pd(OAc)2 (0.9 mg, 0.004 mmol) and rac-BINAP (81 mg, 0.13 mmol) and purged with N2. To the flask was added (R)-tert-butyl 5-bromo-1-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-carboxylate (20 mg, 0.040 mmol), 3-chlorobenzenamine (10 mg, 0.080 mmol), NaOBut (7.7 mg, 0.080 mmol) and toluene (0.5 mL) The mixture was heated at about 95° C. for 2 days. After cooling to about room temperature, the reaction was diluted with EtOAc, filtered through Celite, and concentrated. The crude product was purified by column chromatography (DCM:MeOH, 80:1) to give (R)-tert-butyl 5-(3-chlorophenylamino)-1-(5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-yl)spiro[indoline-3,4′-piperidine]-1′-carboxylate (13 mg, 59%) as a yellow oil. LCMS (APCI+) m/z 546 [M+H]+; Rt=4.24 min.
