Procedure
A mixture of Example 1 (311 mg, 1 mmol), (2-(+)-glycidyl nosylate (311 mg, 1.2 mmol), and K2CO3 (200 mg, 1.45 mmol) in DMF (3 mL) was stirred at RT for 4 hr. The mixture was diluted with ethyl acetate and the solids were filtered. The filtrate was washed with brine, dried, and concentrated. The residue was purified by flash column chromatography (silica gel, 50% ethyl acetate in hexanes) to afford the title compound (340 mg, 92% yield). LC/MS; (M+H)+=369.1
