Reaction Steps

To a solution of methyl 12-cyclohexyl-3-hydroxy-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxylate (150 mg, 0.38 mmol) in N,N-dimethylformamide (2.0 ml) were added potassium carbonate (132 mg, 0.96 mmol) and benzyl bromide (0.07 ml, 0.61 mmol) and the mixture was stirred at 60° C. for 3 hr. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate solution and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure, and the obtained residue was purified by silica gel chromatography (hexane:ethyl acetate=3:1) to give methyl 3-benzyloxy-12-cyclohexyl-6,7-dihydro-5-oxa-7a-azadibenzo[a,e]azulene-9-carboxylate (173 mg, yield 94%).
