For the Mitsunobu reaction of certain analogs, THF was substituted for toluene as solvent. Diisopropyl azodicarboxylate (1.137 mL, 0.005430 mol) was then added dropwise. After 3 d stirring at RT, the reaction was evaporated to dryness. The residue was purified by silica gel chromatography using 0-30% ethyl acetate in hexanes as eluent (Rf=0.38 in 3:1 hexanes/ethyl acetate). Isolated was 0.739 g of product (60%). ESI-MS (M+H+): 366.20.
