To a solution of an alcohol (1.276 mg, 0.075 mmol, see Table 4 for specific alcohol used for each reaction) and 4-(bromomethyl)-N-(2,4-dimethylphenyl)-N-isobutylbenzenesulfonamide (0.031 g, 0.075 mmol) in 2-Methyltetrahydrofuran (2-MeTHF) (1 mL) stirred under nitrogen at room temperature was added solid sodium hydride (1.800 mg, 0.075 mmol) (tip of spatula). The reaction mixture was stirred at 20° C. for 3 hrs. The reaction was carefully quenched with water (5 drops per reaction). The solvent was dried under a stream of nitrogen in the Radleys blowdown apparatus to give the crude product. The sample was dissolved in 1:1 MeOH:DMSO 1 mL and purified by mass directed autoprep on an Xbridge column using acetonitrile:water with an ammonium carbonate modifier. The solvent was dried under a stream of nitrogen in the Radley's blowdown apparatus to give the required product (3.89 mg, 10% yield).
