Participants

Reaction Steps

The above ester (1.3 g, 3.1 mmol) was dissolved in ethanol (10 ml) and a 4 N sodium hydroxide solution (2.3 ml) was added. The mixture was stirred at room temperature for 4 h. A 4 N hydrochloric acid solution was added until pH 1. Dichloromethane (400 ml) was added and 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 re-evaporated with acetone, dissolved in acetone (50 ml) and left for crystallization. This afforded 0.45 g of the title compound as a solid.
