Reaction Steps

This material was prepared in analogy to example 1 step D) from 1-benzenesulfonyl-4-(2-methoxy-ethyl)-piperidine-4-carboxylic acid ethyl ester (0.2 g), dimethylaluminium chloride in heptane (0.9 molar, 0.94 ml) and 4-isopropoxy-aniline (0.1 g) to give the desired 8-benzenesulfonyl-2-(4-isopropoxy-phenyl)-2,8-diaza-spiro[4.5]decan-1-one (0.14 g) as a yellow solid. MS (ESI): 429.18 (MH+).
