2-氨基苯甲酰胺-N-(2-甲基苯基)

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: An oven-dried resealable schlenk tube containing a stir bar was charged with Pd2(dba)3 (4.6 mg, 0.005 mmol), 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl (19.0 mg, 0.04 mmol), 2-aminobenzamide (170 mg, 1.25 mmol) and K2CO3 (173 mg, 1.25 mmol). The tube was capped with a rubber septum, evacuated and backfilled with argon. 2-Chlorotoluene (60 μL, 0.5 mmol) and tbutanol (1 mL) were added through the septum via syringe. The septum was replaced with a Teflon screw cap. The schlenk tube was sealed and put into a pre-heated oil bath at 110° C. The reaction mixture was stirred for 17 h, allowed to cool down to room temperature and filtered through celite with ethyl acetate. The filtrate was concentrated under reduced pressure. Chromatography on silica gel column with 4:1 hexane:ethyl acetate gave 98 mg (87%) of 2-(2-methylphenylamino)benzamide as a white solid and 11 mg (10%) of 2-amino-N-(2-methylphenyl)benzamide as a white solid.
