To a solution of N-(3-{6-methyl-3-[2-(1-methyl-1H-indol-3-yl)acetyl]-3-azabicyclo[3.1.0]hex-6-yl}phenyl)methanesulfonamide (Preparation 117, 55 mg, 0.126 mmol) in anhydrous tetrahydrofuran (1 ml) under a nitrogen atmosphere at 0° C. was added dropwise lithium aluminium hydride (1.0M solution in tetrahydrofuran, 0.26 ml, 0.26 mmol) and the reaction mixture was stirred at room temperature for 3 h. The rapidly stirred reaction mixture was treated sequentially with water (0.26 ml), sodium hydrogen carbonate (250 mg) and ethyl acetate (10 ml). After 30 min, the reaction mixture was filtered and concentrated in vacuo to afford a colourless oil. This was purified by preparative HPLC (condition 8) to give a pale yellow oil which was partitioned between dichloromethane (10 ml) and aqueous potassium carbonate solution (4% w:v, 5 ml). The layers were separated and the organic layer was washed with water (3 ml), dried (Na2SO4), filtered and concentrated in vacuo to afford the title compound as a colourless oil (28 mg, 52%).
