Ethyl bromoacetate → HCID 14856503, compound

Participants

Reaction Steps

Under nitrogen, (21) (2.6 g, 9.3 mmoL) was added portionwise to a stirred suspension of sodium hydride (465 mg of a 60% mineral oil dispersion, 1.25 eq) in dry dimethylformamide (60 mL , from CaH2). After 30 minutes, ethyl bromoacetate (1.3 g, 11.6mmoL, 1.25 eq) was added and stirring was continued overnight. The reaction was then diluted with water (200 mL), neutralized, and extracted with ethyl acetate (3×200 mL). The combined organic phases were washed with brine (3×200 mL), dried (MgSO4), and concentrated. The crude solid was recrystallized twice from ethyl acetate/hexane to provide 1.7 g(50%) of product (22): mp 189°-191° C.
