Reaction Steps

A mixture of 4-bromo-2-methylpyridine 13-1 (516 mg, 3.00 mmol), (4-(aminomethyl)phenyl)boronic acid hydrochloride 13-2 (422 mg, 2.25 mmol), Pd(PPh3)4 (173 mg, 0.15 mmol) and K3PO4 (1.7 g, 8 mmol) in anhydrous dioxane (10 mL) was stirred at 96° C. under argon overnight. After cooling to room temperature, the mixture was filtered through celite and washed with ethyl acetate. The filtrate was concentrated by rotavap and the residue subjected to silica gel column chromatography with 7% ammonia-saturated methanol in dichloromethane as eluent to give (4-(2-methylpyridin-4-yl)phenyl)methanamine 13-3 as an oil.
