To a solution of 2-Methyl-quinolin-6-ol (4.13 g, 0.0259 mol), cis 4-tert-Butyl-cyclohexanol (4.86 g, 0.0311 mol) and triphenylphosphine (9.53 g, 0.0363 mol; Supplier=Aldrich) in tetrahydrofuran (100 mL, 1 mol; Supplier=Acros), cooled in an ice bath, was added diisopropyl azodicarboxylate (7.61 mL, 0.0363 mol; Supplier=Acros) in Tetrahydrofuran (10 mL, 0.1 mol; Supplier=Acros). The reaction mixture was stirred for 72 h allowing to reach room temperature. The solvent was removed under reduced pressure and the residue was taken up in methylene chloride, adsorbed onto silica gel and purified by flash chromatography (0-30% ethyl acetate in hexanes) to give the title compound in 56% yield. ESI-MS (M+H+): 298.3.
