Procedure
To a mixture of EXAMPLE 3A (0.125 g) and triethylamine (0.21 mL) in acetonitrile (3 mL) at 0-5° C. was added methanesulfonyl chloride (0.0404 mL). After 30 minutes, the mixture was concentrated, and the concentrate was purified by flash chromatography on silica gel with 0-30% ethyl acetate/hexanes.
