Procedure

A solution of (6R)-6-(tert-butyl-dimethyl-silanyloxymethyl)-2-hydroxy-3,4,7,8-tetrahydro-2H,6H-5-oxa-1-aza-phenanthrene-1-carboxylic acid tert-butyl ester (0.45 g, 1.0 mmole) in o-dichlorobenzene (150 mL) was stirred at 180° C. for 4 hours. The solvent was removed in vacuum. The residue was purified by column chromatography on silica gel (10% methylene chloride/hexane) to afford 0.23 g (70%) of the title compound as an oil, [α]25D=−61.94° (c=10.7, THF).
