Reaction Steps

(6-benzyloxy-pyridin-3-yl)-[3-bromo-5-(4-methoxy-benzyloxy)-phenyl]-amine. A dry tube was charged with 6-benzyloxy-pyridin-3-ylamine (68 mg, 0.34 mmol), 1,3-dibromo-5-(4-methoxy-benzyloxy)-benzene (126 mg, 0.34 mmol), NaOtBu (46 mg, 0.48 mmol), Pd2(dba)3 (3.1 mg, 0.0034 mmol), BINAP (6.3 mg, 0.01 mmol) and degassed toluene (2 mL). The tube was heated in a microwave reactor at 120° C. for 1 h. After cooling down to room temperature, the reaction mixture was loaded directly on Celite®. Chromatographic purification afforded 6-benzyloxy-pyridin-3-yl)-[3-bromo-5-(4-methoxy-benzyloxy)-phenyl]-amine as a yellow oil (78.8 mg, 47%).
