| Reactant | Sodium Hydroxide | HCID 14798 | — |
| Reactant | Ethyl (1-phenylethyl)malonate | HCID 86169512 | — |
| Solvent | Propan-2-one--water (1/1) | HCID 18366337 | — |
| Product | HCID 18980811 | HCID 18980811 | 65% |
Reaction Steps
The ethyl (1-phenylethyl)malonate is stirred overnight with sodium hydroxide (1.3 eq) in an acetone/water (3:1 by volume) mixture. After concentrating to dryness, the residue is taken up with water (40 mL) and the mixture is then extracted three times with ethyl acetate (25 mL). The organic phase is washed, dried, filtered and concentrated to dryness to yield 3.5 g of 2-ethoxycarbonyl-3-phenylbutanoic acid in a 65% yield in the form of an oil, having the following characteristics: Rf =0.50 [methylene chloride/methanol (9:1 by volume)].
