Reaction Conditions

Reaction Steps

To a solution of diethyl methylmalonate (5.19 g) in 100 mL of THF was added NaH (1.2 g, 60%) at 0° C. in portions. The mixture was stirred at 0° C. for 10 min, and to this solution was then added the bromide intermediate (3.84 g) in one portion. The mixture was warmed to 23° C. and stirred for 1 h before the addition of water. The resulting mixture was extracted with ethyl acetate, concentrated and purified by Biotage (5-10% ethyl acetate in hexane) to give the diester containing some diethyl methyl malonate contaminant as a crude oil.
