실험 절차

(4-{[1-(2-Chloro-benzenesulfonyl)-4-(2-methoxy-ethyl)-piperidine-4-carbonyl]-amino}-phenyl)-acetic acid ethyl ester (2.47 g) in toluene (50 ml) was treated with dimethylaluminium chloride in heptane (1 molar, 5 ml) under an argon atmosphere at RT, and then refluxed for 3 hours. The reaction was then cooled to RT partitioned between AcOEt and 1N aqueous HCl/water. The layers were separated, the organic layer dried over sodium sulphate and the solvent was removed in vacuo to give the desired {4-[8-(2-chloro-benzenesulfonyl)-1-oxo-2,8-diaza-spiro[4.5]dec-2-yl]-phenyl}-acetic acid ethyl ester as a light brown solid. MS (EI): 491.2 (M+).
