Reaction Steps

To a solution of 6-bromo-1,2,3,4-tetrahydronaphthalen-1-one (2.0 g, 8.9 mmol) in toluene (20 mL) was added N-methylaniline (960 mg, 8.9 mmol), Cs2CO3 (4.4 g, 13.4 mmol), BINAP (310 mg, 0.5 mmol) and Pd(OAc)2 (110 mg, 0.5 mmol). The mixture was stirred overnight at 100° C. under nitrogen. The mixture was filtered and concentrated, and the residue was purified by silica gel chromatography (30%-80% EtOAc/Hex) to give 1.52 g (68%) of the title compound as a light brown oil. [M+H] calc'd for C17H17NO, 252. found 252.
