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) in tetrahydrofuran (100 mL, 1 mol), cooled in an ice bath, was added diisopropyl azodicarboxylate (7.61 mL, 0.0363 mol) in Tetrahydrofuran (10 mL, 0.1 mol). The reaction mixture was stirred for 72 h at 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.
