HCID 178422073HCID 178422073, compoundYield 52%

Procedure

Triphenylphosphine (5.14 g, 19.6 mmol) was added to a solution of 3-Methyl-isoquinolin-7-ol (2.08 g, 13.1 mmol) and cis-4-tert-butylcyclohexanol (3.06 g, 19.6 mmol) in Toluene (60 mL, 600 mmol). The mixture was stirred for 15 minutes then Diisopropyl azodicarboxylate (3.86 mL, 19.6 mmol) was added. The mixture was then stirred at room temperature overnight. The solvent was removed under vacuum. The crude product was dissolved in methylene chloride, adsorbed onto silica gel and purified by flash chromatography (0-30% EtOAc in hexanes) to give the title compound in 52% yield. ESI-MS (M+H+): 298.46.
