Procedure
Compound (2) from Example 2, in anhydrous methanol, was neutralized with equivalent amount of lithium hydroxide: The solvent was then removed, and the residue dissolved in a small amount of anhydrous THF. Ether was subsequently added and the solution stored in a refrigerator. The precipitated crystals were filtered and washed with ether.
