Procedure

A solution of the product from Example 2B (0.25 g) in ethyl alcohol (20 mL) was treated with 6M HCl (20 mL) and heated to reflux for 1.5 hours. The ethyl alcohol was evaporated and the aqueous portion basified with 1N sodium hydroxide. The basified solution was extracted with methylene chloride (3×). The combined methylene chloride extractions were concentrated and the residue was purified by flash chromatography over silica gel (10:90:1 ethanol/methylene chloride/saturated ammonium hydroxide) to provide the title compound (0.10 g) which was converted to the hydrochloride salt.
