Participants

Reaction Steps

The above ester (2.5 g, 5.8 mmol) was dissolved in ethanol (15 ml) and a 4 N sodium hydroxide solution (4.3 ml) was added. The mixture was stirred vigorously at room temperature for 5 h. A 4 N hydrochloric acid solution was added until pH 1 followed by dichloromethane (400 ml). The mixture was stirred vigorously for a few minutes and the phases were separated. The organic phase was dried over sodium sulphate and the solvent was evaporated in vacuo. The residue was evaporated twice with acetone, once with ethyl acetate, dissolved in acetone (15 ml) and left for crystallization. This afforded 1.9 g of the title compound as a solid.
