実験手順

50 mmol of 5-benzoylamino-1-hyroxy-5,6,7,8-tetrahydro-naphthalene and 100 ml of anhydrous potassium potassium carbonate are stirred at 50° C. in 100 ml of absolute dimethylformamide for 20 minutes. A solution of 60 mmol of methyl chloroacetate and 25 mmol of potassium iodide in 25 ml dimethylformamide is added dropwise and the mixture is stirred at 50° C. for 6 to 8 hours. It is filtered under the influence of heat, the residue is rinsed thoroughly with ethyl acetate and the filtrate is evaporated. The residue is stirred in a mixture of 10% strength NaOH and ethyl acetate or tetrahydrofuran for 10 minutes. The ethyl acetate phase is extracted by shaking once with 10% strength NaOH, dried over Na2SO4 and evaporated. The residue is recrystallized from ethyl acetate.
