Procedure: A solution of 4hydroxybenzenesulfonic acid (10.0 grams, 43.1 mmole) and sodium hydroxide (3.3 grams, 83 mmole) in water (40 mL) was mixed with a solution of 1-iodo-3methylbutane (11.3 mL, 86.4 mmole) in isopropanol (60 mL) and the resulting mixture was heated at reflux for 2 days. The isopropanol was removed by evaporation under vaccuum. The titled compound, 10.0 grams (87%), was collected by filtration washing with isopropanol. the resulting mixture was heated at reflux for 2 days The isopropanol was removed by evaporation under vaccuum The titled compound, 10.0 grams (87%), was collected by filtration washing with isopropanol

Procedure: Sodium hydride (0.11 g) was added to a solution of 3-azabicyclo[3.1.0]hexane-2,4-dione (0.3 g) in dry tetrahydrofuran (10 ml) under a nitrogen atmosphere at room temperature. The suspension was stirred for 5 minutes and 1-iodo-3-methylbutane (0.53 g) was then added in one portion to the reaction mixture. After stirring for two hours at room temperature, dimethylformamide (5 ml) was added and the reaction mixture was stirred for a further 16 hours at room temperature. The reaction mixture was diluted with dichloromethane and then partitioned with water (20 ml). The aqueous phase was extracted with dichloromethane (20 ml) and the combined organic extracts were washed with water (2×20 ml), dried (MgSO4) and evaporated in vacuo. The residue was purified by chromatography on silica gel (50 g) using 25% ethyl acetate/hexane as eluant to give the title compound as a colourless oil. After stirring for two hours at room temperature the reaction mixture was stirred for a further 16 hours at room temperature partitioned with water (20 ml) The aqueous phase was extracted with dichloromethane (20 ml) the combined organic extracts were washed with water (2×20 ml) dried (MgSO4) evaporated in vacuo The residue was purified by chromatography on silica gel (50 g)
