The mixture was stirred at room temperature for 18 hours, quenched by the sequential dropwise addition of water (2.2 ml), 5M aqueous sodium hydroxide solution (2.2 ml) and water (6.6 ml) and filtered. The filtrate was dried over sodium sulphate and evaporated to give the title compound as a colourless gum (7.5 g, 96%).
