Reaction Steps

Compound 179 (0.037 g, 0.09 mmol) was dissolved in acetonitrile (10 mL) and the reaction mixture was heated at reflux for 3 h. The solvent was removed under reduced pressure and the residue dissolved in a mixture of ethyl acetate (10 mL) and 1M HCl (5 mL). After separating the aqueous layer, the organic layer was washed with additional 1M HCl (2×5 mL), saturated sodium bicarbonate solution (3×5 ml), water (2×5 mL) and saturated brine (5 mL). The solution was dried (MgSO4), filtered, and the filtrate concentrated under reduced pressure to give compound 180. ESI-MS m/z=323 (MH+). The product had nearly totally racemized at this point (chiral purity was 46:54 S:R). The reaction described above and compound 180 are shown below.
