|---|---|---|---|
| Reactant | Sodium Bicarbonate | HCID 516892 | — |
| Reactant | tert-Butyl 4-(2-ethoxy-2-oxoethyl)piperazine-1-carboxylate | HCID 22321826 | — |
| Solvent | Trifluoroacetic acid | HCID 6422 | — |
| Product | Ethyl piperazine-1-acetate | HCID 207112 | — |
Reaction Steps
A solution of 4-ethoxycarbonylmethyl-piperazine-1-carboxylic acid tert-butyl ester in 90% trifluroacetic acid (5 ml) was stirred for 3 h. The mixture was basified with saturated sodium bicarbonate solution and concentrated. The residue was triturated with ethylacetate (30 ml) and filtered. The filtrate was concentrated to leave piperazin-1-yl-acetic acid ethyl ester as a yellow oil (ca 1.5 g)
