Procedure

N-(2,4-dimethylphenyl)-4-hydroxy-N-isobutylbenzenesulfonamide (33 mg, 0.099 mmol), pyridine-4ylmethanol (2.52 mg, 0.148 mmol), triphenylphosphine (39 mg, 0.149 mmol) were pre-weighed into a 4 mL glass vial. Tetrahydrofuran (THF) (0.6 mL) was added followed by diisopropyl diazene-1,2-dicarboxylate (DIAD) (0.029 mL, 0.148 mmol). The vial was capped and stirred at RT for 2 days. The reaction mixture was filtered to remove any insoluble materials. The sample was 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 Radleys blowdown apparatus to give the required product.
