Reaction Steps

The product from Example 38B (0.2 g, 0.33 mmol) was treated with 48% hydrogen bromide in acetic acid (4 mL), stirred for 72 hours, neutralized with concentrated ammonium hydroxide, and extracted with methylene chloride (3×). The combined organic layers were dried (Na2SO4), filtered, and concentrated. Purification of the residue on silica gel (10% ethanol/ammonia saturated methylene chloride) to provide the title compound (0.03 g) which was converted to the HCl salt.
