To a suspension of the 257 (134.6 mg, 0.418 mmol) in THF (4.2 mL) was added 2-phenylacetyl isothiocyanate (111 mg, 0.627 mmol). The reaction mixture was stirred for 1 hr at room temperature, transferred onto a chromatography column and eluted wit a gradient of gradient EtOAc/hexane, 1:1 to 2:1, to provide a beige solid which was triturated with diethyl ether to afford title compound 258a (31 mg, 15% yield) as a white solid. Characterization of 258a is provided in the table 23.
