実験手順

The solid residue obtained in step A was dissolved in 2.5 ml of ethanol and 0.180 ml of aqueous solution 2N NaOH were added. The mixture was heated at 60° C. for 2 hours, the solvent was evaporated and the solid obtained was suspended in water. The pH was taken to 6.5 and extracted with CHCl3. The crude mixture was purified over a SCX cartridge eluting with MeOH/NH3 10:1 affording 0.025 g (yield 77%) of the expected product.
