Ethyl bromoacetate → HCID 13059431, compound

Participants

Reaction Steps

A solution of methyl 4-(1H-imidazol-1-yl)-β-oxobenzenepropanoate (6.1 g, 0.025 mol) in tetrahydrofuran (65 ml) is added slowly to a stirred suspension of 50% NaH (1.2 g, 0.025 mol) in tetrahydrofuran (20 ml) and the solution is stirred for one additional hour. Ethyl bromoacetate (4.5 g) is added followed by refluxing the mixture for 7 to 8 hours. The tetrahydrofuran is removed, the residue is treated with water, and the organic material is extracted with ether. The residue obtained after removal of ether is hydrolysed by heating with 6 N HCl for 7 to 8 hours. The crude acid is finally crystallized from dimethylformamide to yield 3.3 g of the product 4-(1H-imidazol-1-yl)-γ-oxobenzenebutanoic acid.
