Ammonium Chloride → HCID 86667924, compound

Participants

Reaction Steps

To a solution of 6-bromo-3-chloropicolinaldehyde (10.0 g, 45.45 mmol) in 200 mL THF stirring at −78° C. under N2 was slowly added methylmagnesium bromide (3.0 M in diethyl ether, 16.63 mL, 50 mmol). The reaction was stirred at this temperature for 3 hours, and then saturated ammonium chloride was added. The mixture was extracted with EtOAc. The combined organic layers were dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified by silica gel chromatography (0-1% EtOAc/hexanes over 20 minutes) to provide 1-(6-bromo-3-chloropyridin-2-yl)ethanol (8.4 g, 78%).
