To a solution of N-(3-{6-methyl-3-[3-(3-thienyl)propanoyl]-3-azabicyclo[3.1.0]hex-6-yl}phenyl)methanesulfonamide (Preparation 126, 200 mg, 0.49 mmol) in anhydrous tetrahydrofuran (7.5 ml) under a nitrogen atmosphere at 0° C. was added dropwise lithium aluminium hydride (1.0M solution in tetrahydrofuran, 0.99 ml, 0.99 mmol) and the mixture was stirred at room temperature for 2 h. The rapidly stirred reaction mixture was treated sequentially with water (1 ml), sodium hydrogen carbonate (1.0 g) and ethyl acetate (25 ml). After 15 min the reaction mixture was filtered and concentrated in vacuo to afford a light yellow oil. This was purified by chromatography using a Biotage Flash 12™ cartridge packed with silica gel (8 g) eluting with hexane:ethyl acetate (100:0 to 0:100) to afford the title compound as a colourless oil (108 mg, 56%).
