Reaction Steps

15-1 (7.42 g, 11.48 mmol) was placed in a 1L round bottom flask equipped with a magnetic stir bar. Methylene chloride was added and the reaction mixture was cooled to 0°-5°. Hydrogen chloride was bubbled through the suspension with stirring. After about 2 min. the solid went into solution, and soon afterward a second precipitate formed. After bubbling gas through the suspension for an additional 5 min. the reaction flask was warmed to room temperature. After 30 min. the contents of the reaction flask were concentrated. The resulting white solid was the hydrochloride salt of 15-2 and by HPLC analysis was of >99% purity.
