Reaction Steps
To a solution of the compound from step 102b above (60 mg, 0.20 mmol) in 3 mL of ethanol at 0° C. was added saturated HCl in ethanol (10 mL), and the reaction mixture was stirred for 30 minutes at 0° C. The volatiles were removed under vacuum, and the residue was purified on a column of silica gel, eluting with methanol/methylene chloride (5:95). The product was treated with a saturated solution of HCl/EtOH and held under vacuum for 24 hours to afford a white solid.
