実験手順

A mixture of thiomorpholine (1.03 g, 10.0 mmol), 5-bromo-2-iodopyridine (3.69 g, 13 mmol), Pd2(dba)3 (200 mg, 0.2 mmol), xantphos (510 mg, 0.6 mmol) and t-BuONa (1.44 g, 15 mmol) in toluene (50 ml) was stirred under argon at 98° C. for 3 hours. After cooled to room temperature, the mixture was filtered through celite and washed with ethyl acetate. The filtrate was evaporated and the residue was subjected to silica gel column chromatography with 0-5% ethyl acetate in hexanes as eluent to give 4-(5-bromopyridin-2-yl)thiomorpholine 219-2 as solid.
