Sodium Bicarbonate → HCID 19987327, compound

Participants

Reaction Steps

17.7 g of iron turnings are heated to 66° C. in 80 ml of acetic acid (5%) with thorough stirring. A solution of 12.0 g (0.034 mol) of 2-benzylthio-3,5-dinitrobenzoic acid methyl ester in 20 ml of tetrahydrofuran is then slowly added dropwise. After cooling, the batch is neutralised with saturated sodium hydrogen carbonate solution and extracted three times with ethyl acetate. The extracts are washed with water, dried over magnesium sulfate, filtered and concentrated. Crystallisation from diethyl ether gives 8.1 g (82% of the theoretical yield) of product; m.p. 80°-82° C.
