Reaction Steps

To a suspension of 2-oxoindoline-5-carbonitrile (30 mg, 0.190 mmol) in THF placed in a microwave vial were added sequentially 5-(tert-butyldimethylsilyloxy)-2-chloro-5,6,7,8-tetrahydroquinoline (67.8 mg, 0.228 mmol), K2CO3 (52.4 mg, 0.379 mmol), X-PHOS (7.23 mg, 0.015 mmol), and Pd2(dba)3 (3.47 mg, 3.79 μmol). The vial was sealed and flushed with argon. The mixture was heated in a microwave oven at 80° C. for 95 min. The mixture was cooled to RT and diluted with water and ethyl acetate. The organic layer was separated and the remaining aqueous layer was extracted with dichloromethane. The combined dichloromethane extracts were dried over sodium sulfate, filtered, and evaporated to dryness. Amount 32 mg. Yield 40%.
