Reaction Steps

The product of step (a) (16.0 g) was dissolved in a 0.5 M solution of anhydrous lithium iodide in methyl isobutyl ketone (170 ml) and the solution heated under reflux with stirring for 2 hours. After cooling the crude lithium salt was filtered off, washed with acetone and dried. The product (12.0 g) was dissolved in methanol (50 ml) and diluted with acetone (500 ml). The precipitated impurities were filtered off and the filtrate was evaporated to dryness to give the title product as a deliquescent, pale yellow solid (9.5 g). The salt has no sharp melting point and gradually softens and decomposes above 195° C. Elemental analysis indicates the monohydrate:
