Procedure

A mixture of the compound from Step I (4 mg, 0.08 mmol) in 2N aqueous NaOH (1.2 mL) was stirred at reflux temperature for 1.5 h. The solution was cooled in an ice-bath, neutralized with 2 N aqueous HCl and evaporated to dryness. The residue was suspended in MeOH, mixed with silica gel and evaporated. The solid residue was placed onto a silica gel column (packed in a solvent system of CH2Cl2/MeOH: 10/1) which was eluted with a solvent system of CH2Cl2/MeOH: 10/1. The fractions containing the product were collected and evaporated to dryness to yield the title compound (20 mg) as a white solid.
