Reaction Steps

To a solution of 2-nitrobenzyl bromide (1.00 g, 4.63 mmol) and diethyl malonate (0.741 g, 4.63 mmol) in 30 ml of hexane was added potassium carbonate (0.640 g, 4.63 mmol) and 18-Crown-6 (0.012 g, 0.05 mmol). After stirred at 80° C. for 18 hours, the mixture was diluted with water and was extracted with ethyl acetate. The organic layer was washed with water, then with brine, and concentrated under reduced pressure to obtain crude diethyl (2-nitrobenzyl)malonate.
