실험 절차

A suspension of Example 27 (10 g) in methanol (150 ml) was warmed to reflux to obtain a clear solution. To this was added a solution of potassium carbonate (1.16 g) in water (7.5 ml). After heating under reflux for two minutes the solvents were evaporated in vacuo to give a crisp foam. To this was added acetonitrile (100 ml) and the mixture was warmed to reflux, during which time the foam collapsed and started to crystallise. After ten minutes the mixture was allowed to cool to 20° C. then filtered under reduced pressure, washed with acetonitrile (25 ml) and ether (50 ml) to give the title compound as a white solid (10.65 g, 100%). The product is believed to be isolated in the form of its monohydrate. Solubility in water: >250 mg/ml.
