Reaction Steps
To a suspension of 4-bromo-N-methylaniline (500 mg, 2.69 mmol), cyclopropylboronic acid (462 mg, 5.38 mmol), (cyclohexyl)3P+HBF4− (99 mg, 0.27 mmol) and K3PO4 (2.0 g, 9.4 mmol) in toluene (20 mL) and H2O (1 mL) was added Pd(OAc)2 (36 mg, 0.16 mmol) at r.t. under N2. The reaction was stirred at reflux overnight. The reaction was filtered, concentrated, and purified by silica gel chromatography (PE:EtOAc=10:1) to give 268 mg (68%) of the title compound as a brown oil. [M+H] Calc'd for C10H23N, 148. Found, 148.
