Procedure
The compound of Example 20A was dissolved in ethanol and cooled in an ice bath. Gaseous HCl was bubbled through the solution until saturated; the resultant solution was warmed to ambient temperature and allowed to stir overnight under a blanket of nitrogen. The solvents were removed in vacuo; the residue was taken up in bicarb and extracted with EtOAc. The organic layer was decanted, then washed with brine and dried over Na2SO4.
