Reaction Steps

To a solution of 2-bromopyridine (3.05 g, 19.3 mmol) in dry tetrahydrofuran (100 ml) was added dropwise n-butyl lithium in hexane (1.6M, 12.0 ml, 19.2 mmol) under nitrogen atmosphere. After stirring at -78° C. for 30 minutes, thereto was added dropwise a solution of the aldehyde compound (Compound A) (3.00 g, 14.3 mmol) in dry tetrahydrofuran (20 ml), and the mixture was stirred at -78° C. for 2 hours. A saturated aqueous solution of ammonium chloride (10 ml) was added thereto, and the mixture was stirred at room temperature for 50 minutes. The reaction mixture was poured into a saturated aqueous solution of ammonium chloride (200 ml) and extracted with ethyl acetate.
