Versuchsvorschrift

An oven dried Schlenk tube was purged with argon and charged with Pd2(dba)3 (4.6 mg, 0.005 mmol, 1.0 mol % Pd), Cy-BINAP (9.6 mg, 0.015 mmol, 1.5 mol %), and NaOtBu (135 mg, 1.4 mmol). The tube was purged with argon and charged with toluene (2 mL), 4-chlorotoluene (0.12 mL, 1.0 mmol), and benzylamine (0.165 mL, 1.5 mmol). The mixture was heated to 100° C. with stirring until the starting aryl chloride had been completely consumed as judged by GC analysis. The reaction mixture was cooled to room temperature, diluted with ether (20 mL), filtered through celite, and concentrated in vacuo. The crude material was then purified by flash chromatography on silica gel to give 177 mg (90%) of a pale yellow oil.
